对象散全息元件产生的正交象散特性的研究

Normal astigmatic character of astigmatic holographic element

本文从理论上分析了用全息方法制作具有象散特征的一种光学元件——象散全息元件——的可能性,并得到实验上的证明.对由象散全息元件在空间正交方向上产生的象散特性作了较为仔细的研究,给出了实验结果.若用此元件代替普通象散系统,将具有使用方便,经济等优点.

Possibility of making an optical element of astigmatic character (astigmatic holographic element) by holographic method is analyzed theoretically. The astigmatic character in the space normal direction is researched in detail. The experimental results are given. The advantages are easy to operate and ecomomy.
