| 摘 要： | 采用白炽灯作光源、面阵CCD作探测器，用圆偏振和线偏振技术并且改变光源能量对水下目标进行成像。通过比较图像清晰表明用自然光照明无论是采用圆偏振技术还是采用线偏振技术都可提高水下目标成像的清晰度和成像距离，且当偏振条件一定时适应提高光源强度能使图像变得更清晰。

| Abstract: | Using white light as light source and using CCD as detector, the experiment of circular polarization and line polarization imaging for underwater object has been reported in this paper. By comparing the contrast of image, it is shown that either white light circular polarization technique or white light linear polarization technique can make the image for underwater object very clear and increase the contrast of image. |
