摘　　要：水下激光成像技术在海洋底质调查和海洋工程等领域有着广阔应用前景,有效地克服后向散射是激光水下成像技术必需解决的关键问题。概述了距离选通技术和原理,介绍了自制激光水下成像系统、船池实验结果,以及通过实验获得的一些认识。The technique of laser underwater imaging is widely applied to material investigation of the sea floor and oceanographic engineering. To avoid the backscatter light is the core of the technique of the laser underwater imaging. This paper described the principle of range gating to avoid the backscatter, introduced a set of laser underwater imaging system, and its experimental results in boat-pool, and some understandings obtained from experiments.
