| 摘 要： | 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。

| Abstract: | Laser polarization image of underwater objects is studied in this paper by using the laser pulse at the wavelength 532 nm and CCD detector, according to the different degree of polarization between the water medium and immersed objects. The experimental results show that the imaging range in scattering water can be expended to a factor of one and a half. The influence of the various attenuation length and the angle of the polarizer on the contrast of the objects are also discussed in this paper. |
