Abstract
As the key for supplying safe and normal running of whole optical system, it is important to test and evaluate the quality of optical components. The wavefront power spectral density (PSD) can give spatial frequency distribution of wavefront aberration and specify optical components. Based on summarizing the existing PSD specification, one dimension radial PSD is used for specifying the character of the spatial frequency distribution of wavefront aberration about the circular optical surfaces is advanced. Its calculation of PSD for testing circular optical surface with interferometer test instrument is explored in the paper.
