Spatial Light Modulator Based Camera Sees Around Corners

Sebastian Anthony, ExtremeTech:

Ori Katz, Eran Small, and Yaron Silberberg of the Weizmann Institute have shown that they can accurately resolve an object that’s hiding behind nearly opaque obstacles, or around a corner (or in another room, as long as the door’s open. In both cases, the light is scattered by the obstacle (the frosted glass, the corner wall), creating what appears to be white noise — but their camera can take these speckles of noise and enhance them “1000-fold” (the scientists’ words) to recreate the image with surprising accuracy.

Remember when Rick Deckard in Blade Runner was panning around corners in a digital image? Now we know what technology that was based on: SLM.
