Liu Bin, Han Changyuan. A Study of the OTF Measurement for the Microscopic Objectives[J]. Editorial Office of Optics and Precision Engineering, 1990,(5): 54-61DOI:
In this paper a review is given for the image quality test and evaluation of the microscopic objectives and a method of OTF measurement is suggested in which the star image is directly scanned by a slit for sampling the line spread function and transfered into a microcomputer numerically through a A/D converter for FFT calculation to obtain the OTF. The structure of the instrument and the measurement method are described.The performenee examination of the instrument and several examples are presented.
