latest night-vision tech look
The Army's latest night-vision tech looks like something out of a video game
The military's new gadget works by amplifying light that's already out there, either from the moon, stars or sources on the ground. The device senses tiny amounts of photons reflected off seemingly dark objects. Then, the photons pass over an internal surface engineered to convert light into electrons. The electrons are amplified by striking a quarter-sized glass plate that has millions of tiny holes in it. Then, they pass a screen coated with phosphor, a fluorescent substance, to create an image.
