【摘要】The propagation of light underwater is affected by absorption and scattering, which reduce the imaging distance and the contrast of underwater image. In order to suppress the interference of the back scattering, combined characteristics of range-gated image technique and polarization image technique,the polarization image technique based on range-gated method was proposed .According to the principle of time separation of target reflected light by using synchronous control device,and the the difference between target and background depolarization characteristics, the method can be used in submarine imaging. In this paper, the polarization imagining mechanism based on range-gated imaging principle, laboratory equipments and experimental process were discussed in detail. Through experimental analysis, the feasibility of the combination of range gating for backscatter rejection and polarization techniques was proved. This method

离选通的偏振成像方式.基于距离选通的偏振成像一方面利用同步控制装置,时间上分离目标反射光,另一方面通过水体散射光和物体散射光解偏振度的差异来实现成像.本文分析了基于距离选通的偏振成像原理,具体给出了实验装置和实验过程.通过实验分析,得出基于距离选通的偏振成像技术运用于水下成像的可行性,且能大大提高图像的对比度,使其成像质量优于距离选通方式. 【总页数】3页(184-186)
