METHOD AND APPARATUS FOR DETERMINATION OF ANGLE INCIDENCE OF ELECTROMAGNETIC ENERGY

摘要

An optic receiver capable of detecting the angle of incidence of optical energy relative to an airborne frame of reference. Incoming reflected rays are reflected by a one piece detector element into a line image. Power distribution along the line image varies with the azimuth of the target. Computation of target azimuth from the power distribution along the line image is facilitated by photodetectors mounted on this element and associated electronic circuitry.
