摘　　要：随着探测器件技术的进步,新概念的主/被动3D成像技术将主被动探测技术优势有机结合起来,能同时获得目标更加丰富的图像信息(如距离像、强度像、距离-角度像等),从而为正确识别和跟踪目标提供更多的决策信息,大大提高了目标识别概率和可靠性。本文首先介绍了激光3D成像系统的发展现状,重点介绍了林肯实验室研制的Gen-III系统和美国航空航天局的自主精确着陆和危险的检测避免技术项目的 3D闪光激光雷达系统,接着结合HgCdTe雪崩光电二极管(APD)器件的特点介绍了下一代激光3D成像系统主被动探测技术的发展。最后对激光3D成像系统主被动探测技术的未来应用前景进行了展望。With the development of detectors,3D imaging lidar system can obtain distance,intensity,distance-angle image of objects by combining the advantages of active and passive detection.The produced images provide much decision information for proper identifying and tracking object so that target recognition probability and reliability are improved.Firstly,current development state of 3D imaging lidar system is introduced,which focuses on Gen-III system in Lincoln library and 3D flash laser radar system in Autonomous Precision Landing and Hazard Detection Avoidance Technology（ALHAT） by NASA.Next generation of 3D imaging laser radar systems is described through analyzing the characteristic of HgCdTe avalanche photodiode（APD） detector.Finally,the developing prospects of the active / passive detector technology in 3D imaging lidar systems are outlined.
