A New Method of Making Circular Holography Grating

提出了1种新的环形全息光栅制作方法。详细描述了基本原理和具体光路。分析了干涉场并给出了光强分布公式。给出了实验结果,讨论了产生误差的原因。

The paper provides a new method of making circular holography grating light path. The paper describes the basic principles and concrete light path in details. We analyse the interference field and calculate formula on theory, obtaining the distrbuted formula for intensity of light through concrete experiment. We get a number of pictures about circular grating. The author analyse considerable data and contrast pictures by microscope. According to the result of experiment, the paper gives analysis on error of experimental data and discusses the reasons that cause the deflection and makes some modified measures.
