Night vision technology allows humans to see in low light conditions using either image intensification or thermal imaging. It has military, hunting, security, and other applications. Night vision works by either amplifying available light using an image intensifier or detecting infrared radiation using thermal imaging. It has advantages for security, military, and other uses but also has disadvantages like lack of color and high costs.

- 3. WHAT IS NIGHT VISION TECHNOLOGY?????
- 4. INTRODUCTION • The word ‘Night vision’ itself means the ability to see in low light conditions. • Humans have poor night vision compared to many other animals.
- 5. (CONTD…) • So we all might have a question in our mind that is this really possible to see in the dark night? • The answer is……..YES, we can see in the dark night using the proper equipment made by using this technology. • We can see a person standing over 183m(200 yards) away in the dark night.
- 6. HISTORY • Pre 1940’s: Spotlights were used for operations at night. • Due to the nature of these early night vision devices (NVD), they gave away tactical positions. • Military scientists began to think of ways to improve night vision to gain a strategic advantage
- 7. HOW DOES IT WORKS??
- 8. Two technologies are used for night vision: (1)Thermal Imaging (2)Image Intensification
- 10. VARIOUS STAGES …
- 11. THERMAL IMAGING
- 13. NIGHT VISION DEVICES It can be splitted in three broad categories: Scopes Goggles Cameras
- 14. SCOPES
- 15. GOGGLES
- 16. CAMERAS
- 17. APPLICATIONS Military Hunting Wildlife observation Surveillance Security Hidden-object detection Entertainment
- 18. lThis is used in military lAn increase in night time situations for pilots lIt permit user to see object which cannot be seen by our aided eye ADVANTAGES
