  • Optical heterodyne detection system and method
    Patent number: 4305666
    Abstract: A system to achieve heterodyne detection of optical (i.e., infrared, visible and ultraviolet) signal wavefront is disclosed. The system employs a holographic phase grating that, when illuminated by laser radiation, will generate a plurality of wavefronts each of which has a predetermined spatial distribution of amplitude and phase. The grating is part of an optical local oscillator that includes a laser that illuminates the holographic phase grating.
