Abstract

In this paper

a method is given to measure the two dimensional light intensity distribution of star image of microscope objective. It includes the experiment principle

the computation of two dimensional FFT with conventional computer

data fitting and software design.It discusses how to select the valur of measuring azimuth as well as the sampling interval of two dimensional FFT.
