摘要
本文给出了描述光场相干性的基本物理量,从迈克尔逊干涉实验出发,讨论了时间相干性;以矩形谱线的光源为例,计算了时间相干度,简要介绍了傅里叶变换光谱学原理。
This paper first introduces basic physical quantity of coherence and discusses temporal coherence starting from Michael interfering experiment. The author takes light source of the rectangle optical spectrum as an example to calculate time relevant degree and briefly describes Fourier's spectroscopy principle.
