Optical performance depending on the input wavefront distortion is analyzed in terms of StreW ratio. The amplitude of wavefront distortion at the optic axis that gives the system diffraction limited optical performance is described quantatively from the analysis of the Strehl ratio, which is obtained at the image plane using the input wavefront that is characterized by low and high spatial frequency. uency.
