Zhang Xiaohui, Han Changyuan. The Quantitative Measurement of the Two Dimensional Intensity Distribution of Star Image[J]. Editorial Office of Optics and Precision Engineering, 1992,(3): 56-62DOI:
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.
