Abstract

Two-dimensional holographic scanners utilizing an auxiliary reflector are described. The design equations and procedures are derived and outlined. Multiplexing techniques for increasing the resolution are proposed. Scanners of reasonable size and operating at a moderate speed can achieve a total resolution of 10⁷ and a temporal signal of 100 mHz. Applications in the visible and other spectra regions including millimeter or microwave and ultrasonic wave are suggested.
