| 摘 要： | 从像质的概念出发,导出了像质评定的简单公式。在干涉图的每个选定点上测量条纹间的间隔和角度来计算几何光线的斜率误差,然后把这些角度误差画在一张图纸上用以表示几何点扩散函数的角度大小,可以方便而简洁地评定成像质量,避免了复杂的计算。

| Abstract: | Start from the concept of image quality, a simple formula of image quality evaluation is brought out.We calculate the slope errors of light rays by measuring the interference fringe spacings and angles at chosen data points in interference pattern.Then we make a chart of slope error. With this chart,the geometric point spread functions are obtained.Ther efore,it was convenient to evaluate the image quality of optical system and avoid complex calculation. |
