Fig. 1From: To image, or not to image: class-specific diffractive cameras with all-optical erasure of undesired objectsObject class-specific imaging using a diffractive camera. a Illustration of a three-layer diffractive camera trained to perform object class-specific imaging with instantaneous all-optical erasure of the other classes of objects at its output FOV. b The experimental setup for the diffractive camera testing using coherent THz illuminationBack to article page
