What is night vision Technology
"Night Vision” is that technology that provides us with the miracle of vision in total darkness and the improvement of vision in low light environments.
The most common methods as described below are
Image Enhancement,
Thermal Imaging
Low light imaging
Today the most popular and well known method of performing of night vision is based on the use of image intensifiers.
Image intensifier tube
An electro-optical device which converts photons to electrons, amplifies them, then converts them back to photons so the user can see at light levels that are normally too low.
Thermal Imaging
Unlike low light imaging methods they do not require any ambient light at all.
They operate on the principle that all objects emit infrared energy as a function of their temperature.
Equipment
Scopes - Normally handheld or mounted on a weapon, scopes are monocular
Goggles - While goggles can be handheld, they are most often worn on the head. Goggles are binocular
Conclusion
Think of what happens when this night vision technology falls into the hands of hijackers or terrorists or rival forces ?
Thus just like other technologies, it’s a boon when used in a right way but poses a curse when misled
