偏振成像清晰度与成像距离关系的讨论

Relation between Contrast of Image and Imaging Range for Underwater Object

根据水下目标成像清晰度与成像距离关系的计算公式 ,通过实验改变成像距离 ,获不同成像距离时的图像清晰度 ,由实验数据作出成像清晰度与成像距离的关系图 ,并与理论计算值比较。实测曲线与计算曲线的趋势相一致。

According to the equation which expressing the relation between the contrast of underwater image and the imaging range, and by changing the imaging rang experimentally, the figure of C r for experimental data and the figure of C r for theoretical calculation are compared and analysised.
