DARPA develops compact night vision goggles
The Defense Advanced Research Projects Agency (DARPA) has launched a program to develop a multispectral night vision system that will be as light and compact as a pair of traditional goggles..
Despite the fact that night vision devices have been used by the military since the 60s, they are still bulky and heavy, and their field of view is three times smaller than usual. These problems make them uncomfortable and place great strain on the neck, exacerbated by the need for frequent head turns..
Therefore, DARPA has decided to use the latest advances in photonics and optical materials to replace the current complex electronic system with a single flat lens. The researchers plan to achieve the conversion of photons from infrared to the visible part of the spectrum by combining planar optics with new thin materials and methods interaction of light with substances.
The one-step up-conversion process will significantly reduce the size and weight of the device, making it look more like regular glasses..
Another interesting development of DARPA are homing bullets for sniper rifles that are capable of changing their flight path after being fired to ensure that the target is hit.
