How does night vision equipment works:
Night vision equipment can work in two different ways depending on the technology that is implemented.
Image enhancement:-
In image enhancement, light particles, called photons, are collected in small amounts. This amount of light includes the lower portion of the infrared light spectrum. The night vision equipment catches this light and then amplifies it to the point that we can easily observe the image.
Thermal imaging:-
With thermal imaging technology, the night vision equipment operates by capturing the upper portion of the infrared light spectrum. This light is emitted in the form of heat energy by the objects, in place of light reflection.
Night vision technology, have the three generations.
Gen 1,
Gen 1 to Gen 2,
Gen 2 to Gen 3.
The price increases from Gen 1 to Gen 2 and Gen 2 to Gen 3.Each generation offers its own range of increased night seeing capabilities. Visual abilities for Gen 1 range from 10-20%, Gen 2 from 50-60%, and Gen 3 from 75-85%. Similarly, the operational life increases with each of these generations. Operational life of Gen 1 devices is typically 500-1,000 hours, while Gen 2 offers 2,000 hours, and this figure jumps to 10,000 for Gen 3.
