摘　　要：距离选通水下激光成像技术通过控制成像模块的阴极快门时间,从时域上屏蔽大部分可进入成像模块的光信号,能有效抑制水体后向散射对激光成像系统探测性能的影响,提高作用距离。距离选通水下激光成像设备的作用距离与水质条件有关,文章给出了一种关于作用距离的有效简化计算方法,根据该方法,可得出设备在不同水质的作用距离。By controlling the cathode shutter time of the imaging module and shielding most of the optical signals that can enter the imaging module in time domain,the laser range gated imaging technology can effectively suppress the influence of back-scattering of water on the performance of the imaging system and improve the operating range.The operating range of the laser gated imaging equipment is related to the water quality condition.This paper presents an effective simplified calculation method of the operating range,according to which the operating range of the equipment in different water quality can be obtained.
