  • Optical heterodyne scanning type holography device
    Patent number: 5064257
    Abstract: There is disclosed an optical heterodyne scanning holography device capable of recording and reconstructing a holographic image of an object in real time by optical heterodyne-scanning the object, capturing a scattered wave from the object by a photodetector, and converting a heterodyne output current from the photodetector to a spatial light modulator for coherent processing optically.
