摘要：

We describe an experiment that clearly shows the change in optical spatial coherence as a function of source size. The experiment is easy to set up, requires modest equipment, and gives a striking demonstration of the celebrated phase shift of the interference fringes. The experiment yields quantitative results that agree well with theory. Setup and data acquisition are suitable for a 3 h upper division undergraduate physics laboratory.
