Displaying Diffraction Patterns of Aberrations by Using CGH

In this paper a method is proposed for the display of diffraction patterns of aberrationsby using interference-type CGH. The single and compound diffraction patterns of coma,spherical aberration and astigmatism are also given. We have found that the mathod ismore accurate and convenient than the previous methods, and it is very advantageous inthe display of diffrent aberrations. A new way is suggusted for the design of an opticalsystem and the evaluation of the optical image by using CGH.
