INTRODUCTION

  • Night vision tehnology,literally allows one to see in the dark.
  • It is originally developed for military use.
  • Humans have poor night vision compared to many other animals
  • With the proper night-vision equipment,we can see a person standing over 200 yards(183 m) away on a moonless,cloudy night.

types of Night vision technology

  • Biological Night Vision
  • Technical Night Vision

NIGHT VISION DEVICES

NIGHT VISION DEVICES ARE BASICALLY DIVIDED INTO THREE TYPES

  • SCOPES
  • GOGGLES
  • CAMERAS

SCOPES

THEY ARE MONOCULAR NORMALLY HANDHELD OR MOUNTED ON A WEAPON.

goggles

  • THEY ARE BINOCULAR AND WORN ON THE HEAD.
  • Night vision goggles useThermal imaging technology to capture that infrared light.

cameras

USED FOR TRANSMISSION OR RECORDING OF IMAGES MOSTLY IF THE LOCATION IS FIXED.

GENERATIONS

GENERATION 0

THE EARLIEST (1950'S) NIGHT VISION PRODUCT WERE BASED ON IMAGE CONVERSION, RATHER THAN INTENSIFICATION.

GENERATION 1

  • VACUUM TUBE TECHNOLOGY
  • FULL MOON OPERATION
  • AMPLIFICATION: 1,000
  • OPERATING LIFE:2,000 HOURS

11

GENERATION 2

  • FIRST MICRO CHANNEL PLATE APPLICATION
  • ONE-QUARTER MOON OPERATION
  • AMPLIFICATION: 20,000
  • OPERATING LIFE:2,500 HOURS

GENERATION 3

  • IMPROVED MICRO CHANNEL PLATE & PHOTOCATHODE
  • STARLIGHT OPERATION
  • AMPLIFICATON: 40,000
  • OPERATION LIFE:10,000 HOURS

PROS

MORE NATURAL IMAGES

LONGER BATTERY LIFE

See through smoke/fog/dust/sand

WIDER FIELD OF VIEW(FOV)

CONS

MORE EXPENSIVE

LONG START UP AND WARM UP TIME

LARGER OR HEAVIER

IMAGE REQUIRES SOME TRAINING TO INTERPRET

13

APPLICATION

  • MILITARY
  • HUNTING
  • WILDLIFE OBSERVATION
  • SECURITY
  • HIDDEN-OBJECT DETECTION

14

CONCLUSION

  • Today in the 21st century we have come a long way in the development of night vision technology,from the early 1940's.
  • Night vision device are basically designed for defensive purposes but the application within the scientific or the civilian range is often prohibited by law.
  • In present scenario the applications of night vision technology is very essential to combat terrorism which is a major problem being faced by mankind.
