Cathode ray tube technology
This document provides an overview of cathode ray tubes (CRTs), including their components, functioning, applications, advantages, and disadvantages. Specifically, it describes the key parts of a CRT - the electron gun, deflection system, fluorescent screen, and glass tube/base. It explains how CRTs work by using an electron beam to scan and excite phosphor dots on the screen, creating a visible image. Common applications of CRTs mentioned are televisions, computer monitors, radar displays, and oscilloscopes. Advantages include brightness and image quality, while disadvantages are health hazards from radiation and heat generation.
Computer graphics - colour crt and flat-panel displays
CRT monitors displays colour pictures by using a combination of phosphors that emit different colored light.
There are two types - Beam penetration method and shadow mask method
Flat panel displays and plasma panel displays
Flat panel displays such as plasma panels, LCDs, and LEDs are thinner, lighter, and use less power than traditional CRT monitors and TVs. They are commonly used in devices like laptops, calculators, video games, and advertisements. Plasma panel displays specifically work by filling the space between two glass plates with neon gas and using electrodes to make the gas cells glow independently of each other, producing the pixels in the display without the need for refreshing. While brighter than LCDs, plasma displays also have some disadvantages like relatively poor resolution and higher cost compared to CRTs.
Plasma panel
Cathode ray tubes are bulky while plasma displays provide wide screens in only 6 inches of thickness. Plasma displays contain tiny cells of xenon and neon gas between glass plates. A grid of vertical and horizontal electrodes sits behind and above the cells. When charged, an electric current stimulates the gas atoms to release photons which interact with phosphor coating to glow. Plasma displays produce bright, wide screens in thin materials but were previously more expensive than other technologies.
Plasma display devices
Plasma displays use small cells filled with electrically charged gas to illuminate pixels, making them thinner than CRTs and brighter than LCDs. Each pixel is created by an electric discharge between electrodes 100 micrometers apart at a few hundred torrs of pressure. Plasma displays produce bright, wide-color images on large screens over 30 inches diagonally and have very low black levels compared to LCDs, though they consume more power.
Cathod ray tube ppt
The document discusses the cathode ray tube (CRT) technology used in early computer monitors and televisions. It describes how a CRT works by using an electron gun to shoot a beam of electrons that excite phosphors on the screen, producing an image. The document outlines the history of the CRT from its discovery in the 1860s to its use in early TVs and monitors. It also discusses the advantages of CRTs like good color accuracy but notes disadvantages like health risks from radiation and large size.

Lasers
This document discusses the basic principles and components of lasers, including an excitable material, an energy source, and a resonant cavity that uses stimulated emission to produce coherent light. It notes that lasers take advantage of the wave nature of light and its ability to excite electrons, which then release photons when returning to lower energy states. The document also lists some common uses of lasers such as communication, precise energy delivery for surgery, and measurement/imaging applications like surveying and interferometry.
Lecture2 antennas and propagation
This document discusses antennas and propagation. It begins by defining antennas and their use for transmission and reception of electromagnetic energy. It then describes common antenna types including dipole antennas and parabolic reflective antennas. The document discusses concepts like antenna gain, effective area, and the relationship between them. It also covers propagation modes including ground-wave, sky-wave, and line-of-sight propagation. Key challenges like multipath propagation, fading, and different types of noise are summarized. Finally, it discusses techniques to compensate for errors during transmission.
Fibre Optics
Fibre optics transmit information using light pulses through glass or plastic fibers. There are two main types of fiber optic cables: single-mode fibers which are thinner and used for longer distances with less attenuation and dispersion, and multi-mode fibers which are thicker and used for shorter distances with more attenuation and dispersion. Fibre optics use the principle of total internal reflection to keep light signals confined within the fiber's core. Fibre optics have numerous applications including telecommunications, networking, remote sensing, power transmission, and illumination.
Propagat
This document discusses various radio propagation models, their purposes and limitations. It describes common propagation modes like ground wave, diffraction, reflections and scattering. Popular models mentioned include ITU recommendations, Okumura-Hata, Longley-Rice and NRAO TAP which account for terrain, buildings, precipitation and other factors to predict transmission loss over different frequencies and path lengths. However, all models have limitations and may give different results so care must be taken in choosing the right model and interpreting predictions statistically.
Cro(nnm)
The document provides an overview of cathode ray oscilloscopes. It describes the key components of an oscilloscope including the cathode ray tube, vertical and horizontal amplifiers, sweep generator, and trigger circuit. It explains how oscilloscopes can be used to measure voltage, time, frequency, and phase relationships. Measurement techniques like Lissajous patterns are also covered.
Fiber
Optical fibers transmit light and are made of three main parts: a core with the highest refractive index surrounded by cladding with a lower refractive index, and a protective jacket. Light is guided through the fiber due to total internal reflection at the core-cladding boundary as long as the light strikes at an angle greater than the critical angle. Optical fibers have applications in communication systems, sensors, and medicine due to their high bandwidth, immunity to interference, reliability, and ability to transmit large amounts of information over long distances.
Magnetostatics (1)
1) Magnetostatic fields are produced when charges move with constant velocity, originating from currents like those in wires.
2) Biot-Savart's law describes the magnetic field produced by a current element, with the field proportional to the current and inversely proportional to the distance.
3) Ampere's law, in integral and differential form, relates the line integral of the magnetic field around a closed path to the total current passing through the enclosed surface.
Ph 101-4
[1] Maxwell's equations describe the fundamental interactions between electric and magnetic fields and how they propagate as electromagnetic waves.
[2] In vacuum, Maxwell's equations simplify and predict that changing electric fields produce magnetic fields and vice versa, resulting in electromagnetic waves that propagate at the speed of light.
[3] The document derives the wave equations for electric and magnetic fields in vacuum, showing that disturbances in these fields oscillate and regenerate themselves as they travel at the speed of light, representing electromagnetic waves.
Sensors and transdusers1
A sensor is a device that detects and responds to some type of input from the physical environment. It measures an input quantity and converts it into a signal which can be read by an observer or by an instrument. A transducer is a device that converts one form of energy to another. Common sensors include temperature sensors, light sensors, motion sensors, pressure sensors, and humidity sensors. Sensors are used in a wide variety of applications including weather stations, security systems, automobiles, medical devices, traffic control, and many more.
Cylindrical and spherical coordinates shalini
In this Presentation, I have explained the co-ordinate system in three plain. ie Cylindrical, Spherical, Cartesian(Rectangular) along with its Differential formulas for length, area &volume.
Halderman ch047 lecture
The document discusses magnetism and electromagnetism. It explains that magnetism is caused by electron motion and can be generated in materials. Electromagnetism is the interaction between magnetism and electricity. Current flowing through a conductor creates a magnetic field, and moving a conductor through a magnetic field induces voltage. Ignition coils use this principle to generate high voltage for spark plugs. Relays and solenoids are also discussed as applications of electromagnetism.
Longitudinal And Transverse Waves
There are two main types of waves: longitudinal waves and transverse waves. Longitudinal waves involve compression and rarefaction of the transmitting medium, while transverse waves involve oscillation perpendicular to the direction of travel. Polarization is evidence of the transverse nature of waves - polarizers can absorb waves with certain orientations. Many applications make use of the polarized nature of transverse waves, such as sunglasses reducing glare from reflected light and polarizing filters increasing contrast in camera lenses.
Optical Fibres
Optical fibers use total internal reflection to transmit light signals along their core. They have a higher refractive index core surrounded by a lower index cladding. Acceptance angle and modal/material dispersion affect signal transmission. Monomode fibers have a small single-path core to eliminate modal dispersion, while multimode fibers have a larger core allowing multiple light paths and more dispersion. Attenuation and noise also impact signal quality during fiber optic transmission.
Lasers basics mechanism and principles
This document discusses lasers and their applications. It begins by explaining the history and science behind how lasers work, including stimulated emission. It then describes key laser characteristics and different types of lasers such as ruby, He-Ne, semiconductor, and dye lasers. Applications are explored in various fields including medicine, industry, communication, military, and more. Lasers are used for applications like laser eye surgery, barcodes, welding, 3D scanning, printers, and holography.
AP Physics - Chapter 21 Powerpoint
- Magnetic fields are produced by magnets and by moving electric charges like electric currents. A magnetic field has both a magnitude and direction at each point in space and can exert forces on moving charges.
- The magnetic force on a moving charged particle depends on the charge and current, magnetic field strength and direction, and the particle's velocity. Right hand rules can be used to determine the direction of the magnetic force.
- Charged particles moving in a magnetic field experience a force perpendicular to both their velocity and the magnetic field, causing them to travel in a circular path. The magnetic force does no work on charged particles.
Fibre Optics
This document provides an overview of fibre optics, including its composition, operation, advantages, disadvantages, types of communication, cable types, pulse spreading, transmission loss, and conclusions. Fibre optics uses glass or plastic filaments to transmit light signals for communication. It has advantages over metal cables like greater bandwidth, less signal degradation, lighter weight, and security. Installation is more expensive than metal cables. Fibre optics enables both analog and digital communication and comes in step index or graded index cable types.
helium-neon laser
The document discusses the helium-neon (He-Ne) laser, which was the first continuous laser invented by Javan et al. in 1961. It operates at a wavelength of 632.8 nm in the red portion of the visible spectrum. The He-Ne laser consists of a glass tube containing a mixture of helium and neon gases that is excited by an electrical discharge. When an excited helium atom collides with a neon atom, the neon atom becomes excited and subsequently decays, emitting a photon that stimulates further photon emissions to generate the laser beam. He-Ne lasers have various applications including reading barcodes and producing holograms.
1.2 reflection of waves
Here are the key points of comparison between incident and reflected waves:
i. Angle of incidence (i) = Angle of reflection (r)
ii. Wavelength (λ), frequency (f) and speed (v) remain the same.
iii. Direction of propagation - Reflected waves propagate in the opposite direction to the incident waves.
iv. Amplitude may decrease slightly due to absorption at the boundary. Otherwise, the wave remains the same.
v. Phase may be reversed depending on the type of boundary - either in phase or 180° out of phase.
vi. For perfect reflection from a smooth surface, the reflected wavefronts are parallel to the incident wavefronts.
Powerpoint types of optical fiber
There are two basic types of optical fiber: multimode fiber and single-mode fiber. Multimode fiber has a larger core that allows multiple light modes to propagate simultaneously, making it easier to couple light into, whereas single-mode fiber allows only a single mode of light to propagate, enabling higher information capacity over longer distances. Both fiber types were initially characterized as step-index but have since evolved, with multimode fiber now including graded-index types and single-mode fiber featuring more complex designs like depressed clad.
AP Physics - Chapter 18 Powerpoint
The document discusses electric forces and electric fields. It defines key concepts like electric charge, conductors, insulators, and Coulomb's law. It also describes how electric fields are created by charged objects and mapped using electric field lines. The electric field inside a conductor is discussed, with the field perpendicular to the surface at equilibrium.

This document provides information on different types of display devices and monitor technologies. It discusses cathode ray tube (CRT) displays, including their structure, working principle, and technologies such as raster scan and vector scan displays. Liquid crystal displays (LCD) and plasma displays are also mentioned. Key aspects of displays such as pixels, resolution, size, viewing angle, response time, and brightness are defined. CRTs are described as having advantages like high resolution and wide viewing angles, but also disadvantages like large thickness and weight.
8259731.ppt
Cathode ray tubes (CRTs) were a common display technology that used electron beams to excite phosphors on the inside of an evacuated glass envelope. The electron beams were generated by electron guns and controlled by deflection plates and coils to scan across the phosphor-coated screen in a raster pattern, refreshing the image rapidly to prevent flickering. Different phosphors determined the persistence of the light emission and were used together with color masks and intensity control to generate color images on CRT displays. Random scan displays stored images as line drawings and refreshed all lines periodically rather than using a raster scan.
Introduction to cathode Ray Tube.pptx
The document discusses the cathode ray tube (CRT), which contains an electron gun and fluorescent screen. Electrons are emitted from the cathode and accelerated toward the screen. Deflection plates steer the electron beam to create images. The screen contains red, green, and blue phosphor dots that glow when struck by electrons. CRTs were widely used in oscilloscopes, TVs, and monitors but have been largely replaced by LCD, LED, and other modern display technologies due to lower costs.
ITFT-Video display devices
Video display devices use various technologies to visually present electronic information. Common types include CRT, LCD, LED, and plasma displays. CRTs use an electron gun to excite phosphors on the screen and were widely used in monitors and TVs. They can operate in raster or random scan modes. Color CRTs use shadow mask or beam penetration methods. Flat panel displays like LCDs are thinner than CRTs and use light modulation rather than emission to display images.
display devices.pptx
The document discusses various display devices including CRT, flat panel displays, and their components and technologies. CRTs use an electron gun and phosphor-coated screen to create images and come in random scan and raster scan varieties. Components include the electron gun, control electrodes, focusing system, and deflection yoke. Flat panel displays are thinner than CRTs and include LCD and plasma displays.
graphic terminal crt monitor
A CRT monitor works by using an electron gun to shoot a beam of electrons that hit phosphors on the inside of the screen, causing them to glow. The electron beam is scanned across the screen rapidly through the use of electromagnetic deflection coils, creating a raster pattern to form images. Color CRT monitors use three electron beams and triads of red, green, and blue phosphors to produce a wide range of colors. While CRTs produce high quality images and have good contrast, they are large, heavy, and can pose health risks due to electromagnetic field and x-ray emissions.

This document summarizes different types of display devices, including cathode ray tubes (CRTs), raster scan displays, random scan displays, liquid crystal displays (LCDs), and light emitting diodes (LEDs). It describes the basic components and functioning of CRTs, including electron guns, phosphor coatings, and deflection coils. It compares raster and random scan displays, noting that raster displays are better for realistic images while random scans are suited for line drawings. LCDs use polarized light passing through liquid crystals to turn pixels on and off. LED displays use semiconductors to emit light when forward biased, and have advantages over traditional light sources like lower energy use and longer lifetimes.
liquid crystal display
An LCD is a thin, flat panel that uses polarization of light to electronically display text, images, and video. It uses liquid crystals that shift polarization of light when voltage is applied. LCDs have transistors at each pixel to prevent crosstalk and allow higher resolutions, viewing angles, and response times than passive matrix displays. Color LCDs use red, green, and blue subpixels to display a wide range of colors.
Crt display
The CRT display was invented in 1897 and was widely used in early computers and televisions. It works by using an electron gun to produce a beam that illuminates phosphors on the screen, producing light to display an image. The first color CRT monitors used an arrangement of three electron guns and color phosphors to produce a full color image. While CRTs provided high quality images at a low cost, they were large, heavy, and produced electromagnetic fields, leading to their replacement by flat panel displays.

Computer graphics uses computers to draw and display pictures, graphics, and data in pictorial form. It expresses data visually instead of just text. Computer graphics is used in movies, games, medical imaging, design, education, simulators, art, presentations, image processing, and graphical user interfaces. Pixels are the smallest display elements on a screen, each with an intensity and color value. Interactive graphics allow user input to modify images, while passive graphics do not. Common display devices are CRT monitors which use electron beams to excite phosphors and LCD screens which use pixels to control light transmission. Algorithms like DDA and Bresenham's are used to draw lines on these displays.
Igor bishko 1432 impact printers2
Impact printers physically strike paper to print, using electromagnets to move print pins that transfer ink from a ribbon to the paper. The three main types are dot matrix printers, which print one character at a time; daisy wheel printers, which rotate a character wheel; and line printers, which print an entire line at once. Barcode scanners illuminate barcodes with LEDs or lasers, use sensors to read the light reflection pattern, convert it to digital data, and decode it into text sent to a computer. Common illumination methods include single-point LEDs in wands/slots, linear LED arrays, and lasers that can scan from inches to feet away.
Video DIsplay Technologies
Liquid crystal displays (LCDs) are the most common display technology. They work by manipulating the orientation of liquid crystals, which allows light to pass through polarized lenses. LCDs have faster response times than older cathode ray tube (CRT) displays. Other display technologies discussed include organic light emitting diodes (OLEDs), digital light processing (DLP), and plasma display panels (PDPs). Emerging technologies like field emission displays (FEDs) aim to improve on LCD and CRT by allowing electron emission without high temperatures.
Module 4
Electrical discharge machining (EDM) is a machining process that uses electrical sparks to erode material from a workpiece. In EDM, a tool electrode is moved close to the workpiece and an electric current is applied, causing sparks that melt and vaporize small amounts of material. The sparks occur in a dielectric fluid which flushes away removed material. Process parameters like spark frequency, current, and spark gap influence the accuracy and surface finish of EDM.
CG MODULE 1 (S6 CSE)-1.pptx
Computer graphics involves rendering pictures, charts, and graphs on computers rather than just text. It has many applications including movies, games, medical imaging, CAD, education, and simulations. Computer graphics uses pixels - the smallest display elements - to represent images on screens. There are two main types: interactive graphics which allow user input, and passive graphics which do not. Raster scan displays refresh images by sweeping an electron beam across the screen in lines, while random scan displays draw images line by line. Algorithms like DDA and Bresenham's are used to efficiently render lines and circles of pixels.

- 3. RESOLUTION • The maximum number of points that can be displayed without overlap on a CRT. • The number of points per centimeter that can be plotted horizontally and vertically.
- 4. PLASMA PANELS • Also called gas-discharge displays. • Constructed by filling the regions between two glass plates with a mixture of gases that usually includes neon. • Firing applied to a pair of horizontal and vertical conductors cause the gas at the intersection of the two conductors to break down into a glowing plasma of electrons and ions.
- 5. CONDUCTING RIBBONS GAS GLASS PLATES
- 6. Light-Emitting Diode (LED) • A matrix of diodes is arranged to form the pixel positions in the display.
- 7. Liquid Crystal Display (LCD) • These produce picture by passing polarized light from the surroundings or from the internal light source through a liquid-crystal material that can be alligned to either transmit or block the light. • The main principle behind liquid crystal molecules is that when an electric current is applied to them, they tend to untwist. This causes a change in the light angle passing through them. This causes a change in the angle of the top polarizing filter with respect to it. So little light is allowed to pass through that particular area of LCD. Thus that area becomes darker comparing to others.
- 11. LASER PRINTER • It uses a very fine powder known as ‘Toner’. • The photoconducting drum which is the key component of the laser printer has a special coating which receives the positive and negative charge from a charging roller. • A rapidly switching laser beam scans the charged drum line by line. When the beam flashes on, it reverses the charge of tiny spots on the drum, respecting to the dots that are to be printed black. • As soon the laser scans a line, a stepper motor moves the drum in order to scan the next line by the laser. • A developer roller is coated with charged tonner particles. As the drum touches the developer roller, the charged tonner particles cling to the discharged areas of the drum, reproducing your images and text reversely. • As the paper passes through a charging wire it applies a charge on it opposite to the toner’s charge. • When the paper meets the drum, due to the opposite charge between the paper and toner particles, the toner particles are transferred to the paper.
- 13. INK-JET PRINTERS • At the heart of an ink jet printer are a large number of high-precision microscopic nozzles which eject ink onto the paper. • The ink jet nozzles are all mounted together on a moving carriage assembly that moves at high speed back and forth across the paper. • Ink drops are commonly printed at a resolution of 600 or 1200 dots per inch. • Optical encoders precisely control the location of the printed dots, both across and down the page.
