Abstract

When an amplitude-stabilized He–Ne laser beam is scattered by a rotating ground glass with small surface inhomogeneities, the probability density of the instantaneous scattered-wave amplitude is gaussian. This has been verified experimentally in the past few years by several independent groups. In this paper, we suggest the use of the joint photon-count probability distribution p (n = 0, m = 0, τ) to measure the absolute value of the electric-field amplitude-correlation function for random gaussian light fields, and report the results of an experiment in which the gaussian field is produced by scattering a light beam through a rotating ground glass. This procedure offers an alternative to other conventional methods, such as self-beating spectroscopy and irradiance-correlation techniques. The correlation time of the scattered-field amplitude in the present experiment has been measured with an accuracy of approximately 0.8%.
