摘要
本文给出一种光学元件(OE)与全息光学元件(HOE)的组合系统,利用它可以获得大口径高精度准直波、大口径会聚球面波和象散波以及各种形状截面的光波。文中给出了系统的构造原理,阐述了其用途。
A new OE-HOE system has been worked out,with which the large-aperture collimated waves,large-aperture convergent wa- ves,astigmatic waves,or wave beam with cross-section of any aperture shape can be produced.The principle of the system and its applic- ations are described.
