  Optical heterodyne detection is one of the main methods of optical coherent detection.Because optical heterodyne detection gains advantages of much higher sensitivity,accuracy and stronger anti-interference ability than optical homodyne detection,it has been widely used in the fields of laser communication,heterodyne spectroscopy,infrared physics,laser gyroscope,radar,and so on.
