摘要
为了正确评价维纳滤波器的质量并实现优化,以便获得好的重构图像,提出采用调制传递函数(MTF)来评价和优化维纳滤波器,得到很好的效果。
In order to obtain high quality reconstructed images, the modulation transfer function to evaluate and optimize the Wiener filter was recommended. The imaging principle of the ring coded aperture was described. The imaging procedure switched by computer was given. The calculated result by this method agrees with the experimental one.
