Tiny salt-grain-sized camera snaps hi-res full-color images

Researchers at Princeton and the the University of Washington have developed a tiny camera, the size of a grain of salt, which can snap sharp, full-color images. It’s made with a metasurface that captures light, which could be scaled up to turn entire … Continue reading Tiny salt-grain-sized camera snaps hi-res full-color images

Holographic camera reconstructs objects around corners in milliseconds

Blind corners have long troubled drivers, but they might not pose such a hazard for much longer. Researchers at Northwestern University have developed a new holographic camera technology that can peer around corners by reconstructing scattered light wa… Continue reading Holographic camera reconstructs objects around corners in milliseconds
