大视角无畸变两步象散彩虹全息术

Two -Step Astigmatic Rainbow Holography for the Reconstruction of Large - Viewing - Angle and Distortionless Images

提出了一种利用全息光学元件获得大口径会聚象散波的方法.介绍了此种全息光学元件的制作过程,阐述了用全息元件制作大面积、大视角、无畸变的象散彩虹全息图的原理.讨论了放大率匹配问题,并给出了实验结果。

Elaborates a new technique in constituting astigmatic rainbow holograms for the reconstruction of large - viewing - angle , distortionless images using holographic optical elements. Theoretical analysis and experimental results are presented
