摘　　要：介绍了用于潜艇实验的水下微光高速摄像系统,并对设计的关键技术做了论述。根据潜艇上的实际情况,设计了最优的设备工作布局,使全系统能发挥最佳的效果。分析了水下30～40m的光照度,进而设计了适合的水下照明方案,尽量采取微光照明的方式,使环境散射达到最低。最后将该系统应用于水下微光高速摄像试验,实验证明该系统在水下重要武器,尤其是水下潜艇等实验中具有广阔的应用前景。An underwater low light level imaging system for submarine trial is introduced and some key techniques are discussed. According to the practical conditions of submarine an optimized illumination system is designed. For the best imaging quality of underwater high-speed photograph system, by the thorough analysis of illuminance requirement in both object space and image space for high sensitive high-speed camera in the circumstance of low light level between 30 and 40 meter under the water, a plan applied to underwater lighting is designed. Some anti-corrosion methods are used for the stability of the system. The system is applied in underwater low light level high speed detecting and has a wide applicable future in the field of underwater weapons, especially submarine.
