栅绝对衍射率的测量
Absolute measurement of grating diffraction efficiency
摘要
本文提出了一种测量光栅绝对衍射效率的新方法.实验表明,这种方法精确、简单,使用方便,易于推广.测量不确定度优于4×10~(-3).
Abstract
This paper discribes a new method of measuring absolute diffraction efficiency of a grating. The main advantage is that the measurement precision is increased by using multiple diffraction. The experimental setup and results are given. Under nonoptimum conditions the measurement uncertainty is less than 4×10-3.
