ABSTRACT:
A radiation receiver is disclosed which, with no moving parts, detects both the azimuth and elevation of radiation in a panoramic field external to the receiver. The receiver includes at least one radiation sensitive element and a refractor. The refractor includes a plurality of prisms distributed on the walls of the refractor and forming a distributed focal plane adjacent to the refractor. The radiation sensitive element is located in the depth of field of the focal plane, and the image of at least one portion of the source of radiation is focused by the refractor from the far field of the refractor onto the radiation sensitive element. The disclosed combination reduces the possibility of damage by the radiation to the radiation receiver.
