| 摘 要： | 本文通过计算从透镜的入射面到其焦平面间的光程差来计算透镜引起的相位改变，提出一种用计算机设计全息透镜的方法，并考虑光在全息透镜和象平面间传输引起的相位改变，最后用模拟出一全息透镜。

| Abstract: | The calculation of optical path difference between the input plane and the focal plane of a lens is used to compute the phase change introduced by the lens.This paper represents a new way to create computer generated optical elements.The phase change that takes place during the light propagation between the computer generated hologram and the image plane is taken into consideration.A way to plot the synthetic lens are presented. |
