Abstract
Experimental results on the effects of finite-aperture detectors on the statistics of Gaussian light are presented. A laser illuminating a rotating diffusing screen was used to provide a source with a long coherence time, and the photoelectron statistics of a photomultiplier detector were recorded electronically. The data, which were taken with circular apertures and a linear polarizer in front of the detector, agree with calculations of factorial cumulant correction factors published by Cantrell and Fields.
