Using space filter to improve light pipe uniformizer

本文报道了一种用空间滤波改善光管式光学均匀性的技术,该技术使用空间滤波器滤除入射光束中光场突变部分。

This paper describes a technique of using space filter in the light pipe uniformizer. With this filter, the uniformity of illumination of light pipe can be improved. Some parameters of the space filter are calculated and experimental results with it is given.
