Femtophotography is a technique that captures ultra-slow motion images of light pulses propagating through a medium. It works by using a camera that can take trillion frames per second to photograph individual photons reflected from an object at different times, which are then combined to recreate the image. Originally developed in 1970, it is now being researched at MIT to visualize light in motion and help with applications like object detection, collision avoidance, and medical imaging like colonoscopies.

Ultraviolet telescope swag
An ultraviolet telescope is a telescope that examines the ultraviolet portion of the electromagnetic spectrum between visible light and X-rays. It usually uses reflectors instead of lenses to keep glass out of the light path, and must be located at high altitudes or in space to view UV light. An ultraviolet telescope has a detector array sensitive to UV light and functions similarly to other telescopes, but is designed to observe the ultraviolet portion of the spectrum. Examples of UV telescopes include the IUE, EUVE, Hubble Space Telescope, FUSE, and UIT.
A.R.A.D. Autonomous Retrieval and Delivery
The document describes an autonomous robot designed to retrieve and deliver objects in hazardous environments like minefields. It discusses the robot's design using a Vex robotics kit with sensors like ultrasonic rangefinders and shaft encoders. It also details several challenges faced with the robot's faulty initial designs and hardware limitations of the microcontroller that required redesigning and partitioning the robot's program into three parts to accomplish its goals.
E.m. spectrum
The electromagnetic spectrum consists of all possible frequencies of electromagnetic waves, which are classified by their frequency and wavelength and common uses. Radio waves have the longest wavelength and are used to transmit general information, while microwaves are used in microwave ovens to heat food by moving hydrogen atoms. The experiment detected microwave wavelengths by observing melted chocolate spots. Infrared radiation is emitted by thermal agitation and detected by special cameras, while ultraviolet light from the sun is responsible for many tumors. X-rays are used to see hidden objects and gamma rays have the shortest wavelengths; one hypothesis is that dark matter consists of axion particles that transform between gamma rays and photons during supernova explosions.
Equipment Documentation
I will need a DSLR camera, tripod, lighting equipment, and a tracker/slider for smooth camera movement to shoot video.

Mfrm
Magnetic Resonance Force Microscopy (MRFM) is a technique that borrows from Magnetic Resonance Imaging and Atomic Force Microscopy to image biological structures at an atomic level resolution. MRFM uses a magnetic field and laser focused on a cantilever to detect minute interactions between a specimen placed on the cantilever and the magnetic field as the cantilever passes over it. This causes the cantilever to vibrate, and an image is created based on the vibration. MRFM allows for subsurface imaging of structures with atomic detail.

Photography
Photography is the process of creating durable images by recording light or electromagnetic radiation, either chemically or electronically. It was invented in the 1820s but the first permanent photograph was made in 1826 by Nicéphore Niépce using a camera obscura. The camera obscura projects an upside-down image of a scene onto a surface. In 1838, Daguerre took the first photo of a person. France agreed to pay Daguerre a pension in exchange for publicly sharing his process. Features of photography include film loading and ISO/ASA ratings, single lens reflex viewfinders, lens apertures and shutter speeds, natural and artificial lighting, macro and micro lenses, and filters.

LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UP
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.

- 1. PRESENTED BY PRANAVRAM.R FROM & FOR MECHB RIT,RAJAPALAYAM
- 2. Have you seen light?? If not, You can see the images of bullet pulses of light in Femto- photography Femto-photography technique captures , visualizes the propagation of the light pulses in a medium through ulta-slowmotion camera Initially carried out in 1970 by Nils Abramsson in Sweden, presently the research is taken up in MIT Media lab led by scientist Ramesh Raskar, an Indian
- 3. Before passing light During the propagation of light
- 4. The camera that takes trillion frames per second
- 5. Principle behind in it
- 6. Concept ◦ A packet of photons are released which travels around with the speed of the light (Million times faster than ordinary bullet) ◦ The scattering of the packet can shows the light in motion ◦ Each reflected photons reach the camera at different times (each photon frame can forms a individual raw frame) ◦ These frames combine to develop the replica of image
- 7. This is the picture of the hidden mannequin, that is formed by the reflected photons
- 8. Applications Used to identify the unknown object in a place To avoid collisions in the roadsides
- 9. Can be used for rescue operations in buildings etc,. Highly recommended for colonoscopies in medical field
- 10. Thank you
