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.

4.  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.

5.  A tank fromWorld
War II equipped
with a search light
used for night
combat.

6. • Thermal imaging
• Image enhancement

9.  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

10. • 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.

12.  The micro
channel plate
(MCP) electron
multiplier
prompted
Generation 2
development in
the 1970’s.

13.  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.

14.  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.

15.  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

16.  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.

17.  There are many practical everyday uses for NVD,
some of which are:
 Law Enforcement
 Hunting
 Wildlife observation

18.  Security
 Navigation
 Hidden-Object detection
 Entertainment

19.  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.
