本文采用测光谱强度推算透过率的方法,对光栅光强透过率分布规律进行了研究。文章列举了几种振幅光栅的母板、复制品、正弦光栅及其复制品的测量数据和推算结果,并引出若干值得进一步探讨的问题。
In this paper, the method of calculating the transmittance of the measured spectrum intensity is used to study the law of light intensity distribution of the grating. The paper lists the measurement data and the calculation results of several kinds of amplitude grating masters, replicas, sinusoidal gratings and their replicas, and leads to several issues worth further exploration.
