ABSTRACT:
Interference patterns are generated in response to temporally coherent light incident upon an interferometer which directs the interference patterns upon an array of photosensitive elements. The photosensitive elements are connected to generate signals representative of the optical energy respectively incident on the elements. The output signals of the photosensitive elements are averaged by a passive resistor network coupled to the photosensitive elements and the signals generated by the individual elements are compared to the average signal by individual comparator circuits to detect the presence and position of an interference pattern directed upon the array.
