This article is a discussion about distribution of light intensity on the image of the imagery system, through which it brings to light the inner link between geometrical image and diffraction image.
本文通过对成象系统中象面上光强度分布的讨论，揭示了几何光学成象与衍射成象之间的内在联系。
One method is presented for determining focus of thin lens by diffraction image in terms of the study results.
并根据研究结果，提出一种通过衍射图像确定薄透镜焦距的方法。
The BOE designed and made in this paper is capable of converting the incidental laser beam into structural light of 2 dimensional dots array, and the diffraction image is nonlocality.
本文设计、光刻的BOE能将入射的激光束整形成空间二维点阵状结构光，且其衍射像是非定域的。
Base on this principle, a three-beam holography system is set up. The diffraction efficiency and the quality of the diffraction image are shown to be greatly improved by the auxiliary violet light.
