Abstract

The effect of finite-sized sampling apertures in the measurement of the complex degree of coherence of an optical field by the two-beam interference method is examined. The fringe visibility does not go to zero when the magnitude of the complex degree of coherence between the center points of the finite apertures goes to zero. This analysis explains observed errors in earlier experimental work.
