Abstract
Abstract A multi-image single passive sensor depth recovery system is disclosed to determine the depth of an object in a scene, and includes a passive imaging sensor which images radiation from an object at a sensor plane. A lens having a multiplicity of facets located on its surface nearest the object is placed in optical communication with the sensor so that each facet directs radiation from the object to sensor plane to form a corresponding image of the object thereon. The size and shape of each of the facets are selected to position each image on the sensor plane at a predetermined position thereon.
