This document discusses night vision technology. It begins with an introduction and overview of applications such as military, law enforcement, and wildlife observation. It then describes the main technique used, called image intensification, which uses a series of steps to focus available light and create a visible image even in low-light conditions. These include focusing light, releasing electrons, collision amplification through a microchannel plate, and creating a phosphor screen image. The document concludes that night vision technology has advanced significantly since its early military uses and now has applications for combating terrorism as well as civilian wildlife photography.

4. Conclusion

3.  Night Vision signifies the ability to see in the dark which has been possessed by
owls and cats.
 It is originally developed for military use as well as for wildlife photography.
 With the proper night vision equipment, one can see a person standing over 200
m away on a moonless, cloudy night.

4. It is quite easy to see
everything during the day...
But at night, we can see very
little.
Night Vision Technology lets us

5.  Law Enforcement.
 Wildlife Observation.

6.  Military night vision goggles and armed tanks.
 Hidden objects detection.

7. Image Intensification Process
Step 1 :- Focusing the available light. Step 2 :- Electrons released from cathode.
Step 3 :- Electrons enter micro channel plate. Step 4 :- Collision of electrons.

8. Image Intensification Process
Step 5 :- Creation of chained reaction. Step 6 :- Electrons hit phosphor screen.
Step 7 :- Green Image Creation. Step 8 :- Viewing resultant image.

10.  Today in the 21st century, we have come a very long way in the development of
night vision technology from the early 1940’s.
 Night Vision devices are designed for military as well as wildlife photography
purposes but the application within the scientific or civilian range is prohibited by
law.
 Presently, the applications of this technology are required to combat terrorist
activities which is one of the major problems faced by mankind.
