ABSTRACT:
A wide-field optical receiver element for determining the direction of a distant source of electromagnetic radiation. A cylindrical reflecting surface is used in an off-axis configuration to produce line images corresponding to sources over the field of view. A planar detector is located at a plane at or near positions where the line images over the field of view are produced, so that a component of the angular direction of the source can be determined from the position of the line image on the detector.
