主要介绍了法国研究人员开展距离选通激光成像仿真所使用的软件SE-Workbench和OSMoS及其仿真方法与流程，给出了复杂场景中目标被动成像与激光主动成像的仿真结果示例，讨论了激光主动成像仿真的一般流程和应注意的方面。可为国内开展激光成像仿真研究提供参考和依据。

This paper mainly introduces the software SE-Workbench and OSMoS used by French researchers in their research on range-gated laser imaging simulation. The simulation sequence and steps are introduced, and the passive imaging and laser active imaging results of target under the complicated condition are given. The general simulation flow of laser active imaging and the aspects needing attention are discussed. The contents can be taken as a reference for the domestic simulation research.
