Components of Remote Sensing
Remote sensing involves collecting data about objects without physical contact. It uses sensors on platforms like satellites and aircraft to detect electromagnetic radiation reflected or emitted from targets. The key components of remote sensing are: (1) an energy source like the sun, (2) interaction of the energy with the target, (3) sensors that record the energy, (4) transmission of the data to processing stations, and (5) analysis and interpretation of the data to extract information. Common sensors detect radiation in the visible, infrared, and microwave portions of the electromagnetic spectrum.

Spectral Signature
Spectral signatures are the specific combination of electromagnetic radiation emitted or reflected at different wavelengths that can uniquely identify an object. A spectral signature depends on factors like the solar angle, view angle, surface wetness, and surrounding materials. While spectral signatures can indicate the composition of stars or distinguish between minerals based on their chemical makeup, they have limitations and may not always provide enough information, such as indicating the desired parameter for vegetation or simulating what a satellite sensor would see due to differences between laboratory and field measurements.

Dichromatic light measurements yielded an average wavelength of 624nm and difference of 13nm, within 5.7% and 182% of accepted values respectively. Broad spectrum light created fringes across the visible spectrum without distinct patterns.

Remote sensing concept, history and principles
Remote sensing involves obtaining information about objects or areas from a distance, without physical contact. It works by detecting electromagnetic radiation from targets. There are several key principles and stages to the remote sensing process. Energy from the sun or another source illuminates the target. As the energy interacts with the atmosphere, it can be scattered, absorbed, or transmitted. The energy then interacts with the target via absorption, transmission, or reflection. Sensors then record this energy, which is processed and interpreted to extract useful information and apply it for various purposes. The history of remote sensing dates back to the early use of cameras on balloons and aircraft, with significant advances driven by space programs in the late 20th century.
Spectrophotometer
A spectrophotometer measures the amount of light absorbed by a sample by directing light through the sample and detecting the intensities of light at different wavelengths. It was invented in 1940 and provided quick, accurate results compared to older techniques. A spectrophotometer uses dispersion devices like prisms and filters to separate light wavelengths and detectors to measure light intensities. It can be used to identify compounds, determine concentrations, detect impurities, study chemical kinetics, and more.
Spectrometer
Spectrometers are instruments that identify substances by analyzing the wavelengths of light they absorb or emit. They work by dispersing light into a spectrum of component wavelengths using a prism or diffraction grating. Each element has a unique spectral pattern that can be used to identify it. Sir Isaac Newton invented an early spectrometer in the 1600s, and later scientists like Kirchhoff and Rydberg made advances that allowed spectrometers to accurately measure atomic structures and energy levels. Modern spectrometers are used across many fields including astronomy, archaeology, chemistry, and medicine to analyze material compositions and properties.

Microscopes are optical instruments that magnify very small objects like cells. There are two main types - optical microscopes, which use visible light, and electron microscopes, which use electrons. Optical microscopes include simple, compound, and special purpose types. Compound microscopes have object and ocular lenses and can magnify up to 2000x. Electron microscopes can achieve much higher magnifications, with scanning electron microscopes magnifying up to 1 million times and transmission electron microscopes up to 1 billion times.

A microscope is an instrument used to magnify small objects that are too small to be seen by the naked eye. It works by using lenses to produce enlarged images of objects placed on its stage. The document discusses the basic parts and functions of microscopes, including the optical and illumination systems, as well as different types such as simple, compound, light, and electron microscopes. It also explains key microscope concepts like magnification, resolution, and oil immersion which are used to view specimens clearly.

Microscopy presentation
This presentation is about the introduction of microscopy, its history, parts of a microscope and different types of microscopes along with a brief discussion of their working principles.
Histological tools
This document discusses various histological tools used to study tissues at the microscopic level. It describes light microscopes, which use visible light and magnification to examine thin tissue slices stained with histological dyes. Electron microscopes are also covered, using electron beams instead of light for higher resolution imaging of cell structures. Specific techniques covered include fluorescence microscopy using fluorescent dyes, polarizing microscopy examining birefringence, and transmission electron microscopy producing 2D images of cell organelles. The history and development of microscopy from early simple microscopes to modern compound and electron microscopes is summarized.

A microscope (from the Ancient Greek: micro- "small“ and scope-"to look") is an instrument used to see objects that are too small for the naked eye
Microscope
Microscopy is used to study microorganisms that are too small to be seen with the naked eye. Bacteria are typically 2-5 μm in size, below the resolution of the human eye, so microscopy is needed. There are different types of microscopes that provide magnification and resolution, including brightfield, darkfield, phase contrast, fluorescent, and electron microscopes. Each type has a specific working principle and applications - for example, phase contrast microscopy can be used to study microbial motility while living cells are visible. Microscopy allows rapid identification and detection of organisms in patient specimens and provides diagnostic information in microbiology.

This presentation talks about one of the most important technique in biology which is microscopy. The inclusions are the history of microscope, different types/kinds/classifications of microscope nowadays and the parts of a simple compound microscope
Laporan Praktikum Biologi Dasar - How to use the microscope
The document provides instructions for using a microscope correctly and safely. It was a report from a biology practicum conducted by Nur Pratiwi. The practicum taught students how to use microscopes to observe the smallest structures of organisms. It covered preparing the microscope, controlling the light, adjusting the lens distance, making simple microscope slides, and changing magnifications. The goal was for students to learn proper microscope procedures.

Optical microscope
The document discusses optical microscopes, which use visible light and a system of lenses to magnify small samples. Some key points:
- The first compound microscope was created in the late 16th century by Dutch spectacle makers Zacharias Jansen and his father Hans.
- There are different types of viewing heads including monocular, binocular, and trinocular.
- Magnification is calculated by multiplying the magnification of the eyepiece and objective lens. Maximum normal magnifications are 10x for eyepieces and 100x for objectives.
- Optical microscopes have applications in fields like microelectronics, biotechnology, medical diagnosis, and industrial measurement and quality control.
2. Microscopy (Biochemistry)
This document provides an overview of microscopy including:
