ABSTRACT:
The specification discloses an optical technique for retrieving images of geometric shapes from a cluttered background in a photographic record by means of amplitude and phase filters configured according to the particular shape sought to be retrieved. A Fourier transform of the record is filtered with filters of both types and light representing the desired shape, if present, is brought to a focus in an image plane.
