  2. 2. Overview:• INTRODUCTION•NIGHT VISION WORKING•BASIC TECHNOLOGIES•INFRARED ILUMINATORS•GENERATIONS•APPLICATIONS•CONCLUSION•REFERENCES
  3. 3. INTRODUCTION• Night Vision scopes and binoculars are electro-opticaldevices that intensify (or amplify) existing light instead ofrelying on a light source of their own.• Night vision googles capture the image even in the dark inthe infrared region.
  4. 4. HISTORY: At first, sniper riffles had night vision technologyincorporated for the ability to see enemies from adistance - this proved to have a dramatic effect in thecourse of the war. Since the Germans found theusefulness of night vision, they began developing newtechnology to successfully dominate the night.
  5. 5. How Night Vision Works Infrared Light:
  6. 6. Basic TechnologiesNight vision work in two very different ways, dependingon the technology used Image enhancement Thermal imaging
  7. 7. THERMAL IMAGING: It is quite easy to see everything during the day Thermal imaging lets you see again
  8. 8. Thermal Imaging Devices:•Un-cooled•Cryogenically cooled
  9. 9. The basic components of a thermal-imaging system
  10. 10. INFRA-RED ILUMINATORS
  11. 11. Working of Image Enhancement:
  12. 12. Thermal Imaging Process:
  13. 13. NIGHT VISION DEVICE: A NVD is a optical instrument that allows images to beproduced in levels of light approching total darkness. Night vision devices were first used in world war IIAnd came into wide use during the Vietnam war. Night vision device is also termed as Night OpticalDevice(NOD).
  14. 14. Generations of NVD: Generation 0 Generation 1 Generation 2 Generation 3 Generation 4
  15. 15. Night Vision Equipment : Scopes Goggles Cameras
  16. 16. Applications: Military Law enforcement Hunting Wildlife observation Surveillance Security Navigation Hidden-object detection Entertainment
