利用自行研制的水下距离选通成像系统在实验水池中对水下靶板进行成像探测,通过改变探测激光能量和像增强器增益,研究了不同系统参数对实际成像探测效果的影响。通过对实验数据的分析,得出了只是提高探测激光能量与ICCD增益不能继续改善探测图像质量,系统参数与探测结果之间存在最优化关系的结论,为水下距离选通成像系统设计提供了有益的结论和指导。

The influences of underwater range-gated imaging systems parameters on image quality are investigated experimentally by changing laser power and voltage on the image intensifier. These experiments are carried out in experimental pond and based on underwater range-gated imaging system that designed by us. The experimental data suggests that raise up the laser power and the voltage on image intensifier cannot always improve the image quality. There will be an optimized solution for the underwater range-gated imaging systems design and parameters.
