Abstract
A device for use in an interferometer, and the combination thereof, the device itself combining the functions of filter, beam combiner, and modulator. In structure, the device includes a relatively small glass plate, which has deposited on opposite faces thereof two extremely small elliptical mirrors which each function as a reflecting spatial filter. In the improved interferometer which includes such a device, reference and signal beams are produced from a single coherent source. The signal beam is spatially filtered by the mirrors and directed to a target. The returning signal beam, reflected from the target, is combined with the reference beam by the mirrors to form a composite beam which forms interference patterns, from which can then be extracted, with extremely high resolution, information concerning the physical characteristics of the target.
