The military’s new gadget works by amplifying existing light, 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. Traditionally, a green phosphor is used, which is why green-hued night-vision imagery is well-known. But Elbit’s latest device uses white phosphor, producing black-and-white images, which officers say creates more contrast and greater clarity at night. “Generally, when you think of night goggles, you think of ambient green light, which is helpful, but this is an improvement on that and allows for better accuracy,” The Army’s latest goggles include an outline mode, which creates glowing white outlines. There’s an augmented reality overlay that can display navigation instructions and maps. The goggles can also connect wirelessly to others in the platoon, so if a soldier spots something, they can mark that object in cyberspace and have it show up on other people’s binoculars.
