Introduction
Night vision technology has shaped history.
Pre 1940’s: Flares and spot lights were used for operations at night.
Introduction Cont
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.
Early Development
The first night vision devices (NVD) were created during WWII.
Functioned by placing an infrared filter over a searchlight.
Fighters would use special binoculars to see using the light from the searchlights.
Many problems came from this night vision method.
There were many disadvantages to using the searchlights and flares.
The actual searchlight was massive and had to be mounted on a truck or tank.
Both the Allies and Nazi’s had this technology, so they each could see the others light.
The images created were streaky and distorted.
The acceleration of electrons cut the life of the image intensification tube, which was the most important and expensive part of the NVD, very short.
Military scientists began planning a revised design.
Current Generations
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.
Conclusion
In conclusion I believe that is wonderful how something originally designed for destruction, can now help people on an every-day basis.
Personally, NVD have saved my brother-in-law from harm in his job through NVD navigation technology.
This is truly amazing technology.
