摘要
本文用几何光学的理想像面、光强分布等理论,对付里叶光学中的滤波对成像、像面对比度的影响,进行了研究和解释。文章还通过合理简化,避免了付里叶光学中繁杂的数学运算。
This paper explaines the effects of filtering waves on the images and the contrast degree in the field of Fourier optics with ideal images and light intensity distribution of geometric optics. It makes reasonable simplification, keeps off mathematically complex operation. This is an easy way to understand.
