激光距离选通成像技术是当前国内外不断发展且应用有效的水下光电成像技术之一，国外20世纪90年代后陆续公开了一些水下光电成像探测系统和实验结果。结合海洋资源勘探、水下救援和侦察等应用领域的需求，全面介绍并对比分析了当前国内外典型水下激光距离选通成像装置和性能水平，讨论了其技术特点，对水下激光距离选通成像技术的发展和装置应用具有意义。

Abstract：Laser range-gated imaging is one of the major and effective technologies for underwater opto-electrical imaging. Domestic and foreign countries have been making great efforts to cultivate this technology. Some underwater opto-electrical imaging systems and experimental results, made by foreign countries, have become available since 1990s. This paper will give comprehensive performance analysis and comparison of existing underwater laser range gated imaging equipments, which can be applied to exploration of marine resources and underwater rescue/reconnaissance. The analysis in this paper is of great significance for the development of underwater laser range-gated imaging technology and equipment.
