Power spectral density measurement for circular optical surfaces
As the key of supplying the safe and normal running of the whole optical system,it is important to test and evaluate the quality of optical components.The wavefront power spectral density (PSD) can give the spatial frequency distribution of wavefront aberration and specify the optical components.Based on summarizing the existing PSD specification,one dimension radial PSD be used for specification the character of the spatial frequency distribution of wavefront aberration about the circular optical surfaces is advanced,its calculation about PSD in testing circular optical surface with coordinate measure machine are explored in this article.
