DARPA's Super-Resolution Vision System uses heatwaves to magnify targets
DARPA's Super-Resolution Vision System (SRVS) may not be as cool as the threat-sensing binoculars we saw a while back, but it may prove a little more practical. The prototype scope takes advantage of something called "atmospheric turbulence-generated micro-lensing" to provide three times the resolution of current diffraction-based scopes. In other words, if soldiers can see you more clearly, they can make an informed decision on whether or not to shoot you.
