Abstract

In the innovative development of social economy, the 3 d imaging laser radar has been widely used in military and civil fields, its dispersion rate of small, high resolution, fast imaging speed of utilizing scanning laser active 3 d imaging technology meet system quickly stable imaging the basic requirements, such as 3 d imaging laser radar technology at present stage is to explore the main direction. For scanning-free liDAR, in the work of long-range non-cooperative target, 3D imaging and detection, the number of echo photons falling on the pixel of detector array is small because the echo is relatively weak. Therefore, on the basis of understanding the current research status of detection technology and system in recent years, combined with the principle of laser heterodyne detection and the statistical principle of photon counting detection, this paper constructed a system ranging accuracy model, and studied the signal-to-noise ratio of photon pulse heterodyne detection system by using random phase-amplitude vector theory. Finally, a photon pulse heterodyne detection system which combines photon technology detection module and pulsed laser heterodyne detection module is obtained.
