Because of the computer optical elements can shape the laser beam to arbitrary shape, so, in this paper we mainly study the designation and the experimentation of the computer optical elements.

由于计算机光学元件能充分有效地产生任意形状的光波波面，所以，本文主要涉及到研究计算机光学元件的理论设计、计算机模拟、实验研究。

This paper discusses the composition and optimum design of the computer originated holographic optical elements (COHOE). The preliminary experimental result with a special wavefront is presented.

本文计论了计算机源生的全息光学元件（COHOE）的合成及优化设计问题，文后给出了一个实际的结果，得到了特殊曲面的波面。
