Abstract

The physical conditions for observing the longitudinal spatial coherence of light of an extended thermal source in interference experiments are defined. For experimental verification of these conditions a Michelson interferometer with a longitudinal scanning mirror was used. The influence of the longitudinal spatial coherence of thermal light on a fringe envelope is demonstrated experimentally.

摘要

定义了在干涉实验中观测扩展热光源光的纵向空间相干性的物理条件。为了对这些条件进行实验验证，使用了带有纵向扫描镜的迈克尔逊干涉仪。通过实验证明了热光的纵向空间相干性对条纹包络的影响。
