  1. 1. DEPARTMENT OF ELECTRICAL ENGINEERING Submitted to Mr. Hemant Amahiya Sir, Lecturer DEPTT.OF ELECTRICAL ENGINEERING JEC,JABALPUR Submitted By SUBHASH DHAKAR (0201EE071056) V th SEM, EE YEAR:2009
  2. 2. • “ Can you see in dark?” • The answer is most definitely yes. with the proper night -vision equipment,you can see a person standing over 200 yards (183 m) away on a moonless, cloudy night. • Ability to see in dark night.
  3. 3.  The first night vision devices (NVD) were created duringWWII. • Pre 1940’s: Flares and spot lights were used for operations at night. • Functioned by placing an infrared filter over a searchlight.
  4. 4.  A tank fromWorld War II equipped with a search light used for night combat.
  5. 5. • Thermal imaging • Image enhancement
  6. 6.  The screen was purposefully colored green due to the scientific fact that the human eye can differentiate more shades of green that any other color
  7. 7. • The starlight scopes of the 1960’s have three image intensifier tubes connected in a series.  During this time period the first “Generation” of NVD began using intensified natural lighting.  The power of Generation 1 NVD was put to the test in theVietnamWar.
  8. 8.  The micro channel plate (MCP) electron multiplier prompted Generation 2 development in the 1970’s.
  9. 9.  These thermal imagers were expensive, so in 1973 scientists created a common module that made it less expensive, and more ideal for military use.  The generation 2 NVD were first put to the test by US forces in the early 1990’s during Operation Desert Storm in Kuwait.
  10. 10.  The currently generations of NVS are generations 3 and 4.  Generation 3 is much like generation 2 except for it has a substantially longer life, as well as more defined images.  Generation 4 has less noise than generation 3, however it has shorter life.
  11. 11.  Here is a chart comparing the life in hours of the intensification tube for generations 1-3 Generation 1 Generation 2 Generation 3 2,000 hours 2,500- 4,000 hours 10,000 hours
  12. 12.  Development of NVD up until the 1980’s was completely focused around military purposes. • In the 80’s, companies in the US and Europe took NVT and found ways to improve everyday civilian life.
  13. 13.  There are many practical everyday uses for NVD, some of which are:  Law Enforcement  Hunting  Wildlife observation
  14. 14.  Security  Navigation  Hidden-Object detection  Entertainment
  15. 15.  In conclusion I believe that is wonderful how something originally designed for destruction, can now help people on an every-day basis.  This is truly amazing technology.
