NIGHT VISION TECHNOLOGY
ABSTRACT

A night vision device (NVD) is an optical installment that allows images to be produced in levels of light approaching total darkness. They are most often used by the military and law enforcement agencies, but are available to civilian users. The term usually refer ....etc

Night vision technology was developed by the US defense department mainly for defense purposes ,but with the development of technology night vision devices are being used in day to day lives. In this seminar of mine I wish to bring out the various principles of working of these devices that have changed the outlook both on the warfront and in our common lives. Night Vision can work in two different ways depending on the technology used. 1.Image enhancement- This works by collecting the tiny amounts of light including the lower portion o ....etc

Night Vision technology consists of two major types: image intensification (light amplification) and thermal imaging (infrared). Most consumer night vision products are light amplifying devices. Light amplification technology takes the small amount of light, such as moonlight or starlight, that is in the surrounding area, and converts the light energy (scientists call it photons), into electrical energy (electrons). These electrons pass through a thin disk that's about the size of a quarter and contains over 10 million channels. As the electron ....etc

Seminar Report on Night Vision Technologies



ABSTRACT

Night Vision technologies encompass techniques of image conversion, image intensification and thermal imaging. Each has distinct characteristics and capabilities.
The current image intensification technology -- utilizing photocathode, phosphor screens and micro channel plates -- illustrates the technology of light amplification and image resolution.
