用计算全息显示象差衍射图

本文提出了用干涉型计算全息图显示象差衍射图,并给出了彗差、球差和象散的单个象差衍射图以及它们的组合象差衍射图。此方法比以往各种方法具有显示精度高和制作方便的优点,而且非常灵活。提出了用象差显示技术作光学设计的新方法以及在象质鉴定中运用CGH技术的可能性。

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.
