ABSTRACT:
A camera in accordance with the invention comprises a coherent light source from which is formed an object illuminating beam and a pumping radiation beam, and an interaction medium for receiving the pumping wave and the imaged wave reflected from the illuminated object. This medium diffracts in real time a replica of the imaged wave which is reflected from the object.
