| 摘 要： | 报道了用圆偏振技术进行水下目标成像结果并分析了用圆偏振技术提高图像清晰度的原因:推导了水下目标最远成像距离的计算公式,在衰减常数α为0.5的水体中,目标放在1.5m处,测量出用圆偏振成像系统成像所得图像对比度C为4.1,通过r0和C可计算出圆偏振成像系统的最远成像距离r为1.92m,与实测距离相差0.08m,相对误差为4%。

| Abstract: | The contrast of the polarization image was measured to be 4.1 and the imaging range was 1.5 m. According to the formula expressing the relation between the contrast for polarization image and the attenuation of water, the farest imaging range with polarization was calculated as 1.92 m. |
