Due to its unique advantages in optical detection of weak signal targets, single photon three-dimensional detection technology has important application prospects in space target detection, aerial target detection, long-distance early warning detection, and has received widespread attention in recent years. For active scanning imaging single photon detection systems, to expand the operating range and improve scanning speed, the receiving aperture and receiving field of view angle continue to increase. However, for highly integrated Geiger APD single photon detectors, the large receiving aperture and field of view bring an increase in the number of background noise photons, which can cause the detector to frequently enter the dead zone and bring a large number of blind spots to the scanned image. In response to this issue, it is proposed that using multi lens diversity reception and joint single photon information processing can achieve suppression of the dead time of single photon detectors, thereby effectively improving the detection probability of the system and reducing the number of blind spots in scanned images. This has been verified through simulation and experimental systems.
