摘　　要：阐述了基于人眼安全激光的短波红外(SWIR)选通成像技术的基本原理;依据选通成像系统对接收成像探测器的要求,对满足选通成像条件的三种SWIR焦平面器件,即HgCdTe APD FPA、InGaAs/InP TE EBCMOS和InGaAs FPA进行了性能介绍;结合基于这三种探测器的典型选通相机以及人眼安全激光选通成像系统,对这三种探测器进行了简要性能分析和对比,并给出了系统及探测器选择的建议。The basic principle of the eye-safety SWIR laser range gated imaging technique is presented. Based on the range-gated imaging system’s requirements,the performance of three typical SWIR FPA sensors （InGaAs FPA,InGaAs/InP TE EBCMOS and HgCdTe APD FPA）is introduced. Tests with the typical SWIR gated cameras with three sensors are made. Three sensors’performance is analyzed and compared. Finally the suggestion for sensor selection is given.
