采用波长532nm的激光器作光源，面阵CCD作探测器，利用水中粒子和物体散射光解偏振度的差异，本文研究了水下物体的激光偏振成像。结果表明，采用偏振技术可使水下成像距离扩展至15倍左右。本文还讨论了不同衰减长度和偏振器的不同偏振角度与图像对比度的关系。
The wavelength of 532nm laser is used as the light source and the array CCD is used as the detector. By using the difference of the polarization degree of light scattering by particles and objects in water, this paper studies the laser polarization imaging of underwater objects. The results show that the use of polarization technology can make the underwater imaging distance expanded to about 15 times. This paper also discusses the relationship between different attenuation lengths and different polarizer polarizer angles and image contrast.
