Single photon detection and laser heterodyne detection are important tools for detecting weak echo light, and the extraction of multidimensional information from weak echo light is currently an important area of laser sensing. However, in practice, background noise and decoherence of the echo light can seriously affect the perception of multidimensional information from single photon detection and heterodyne detection techniques. These problems in the detection of weak echo light are difficult to solve effectively by using conventional solutions. The quantum heterodyne precision measurement method is a new measurement method based on single?photon detection combined with heterodyne detection, which can overcome the shortcomings of single?photon detection sensitivity limited by background noise. In addition, the quantum heterodyne has extremely low requirement for local oscillation intensity, which can effectively reduce the requirement for local oscillation intensity in large array heterodyne detection. This paper further summarises and analyses the research developments in quantum heterodyne precision measurement methods. The review and analysis of the existing research results will help to understand and grasp the current research status and problems of quantum heterodyne precision measurement method, and lay the foundation for the future development of quantum heterodyne precision measurement methods.
