分振幅法制作全息光栅实验的改进

The Improvement of the Experimental Facilities for Making of holographic gratings

分析用传统光路制作全息光栅质量不高的原因。提出了全息光栅的拍摄光路改进方法,讨论了实验中的几个关键问题。

In this paper , the cause of the lower quality in mading the holographic grating using the traditional optical path is analysised and a new approach of shooting optical path is given to improve the quality of holographic grating. Some key problems in this experiment are also discussed.
