Abstract
It is well known that the three-dimensional dimension of laser speckle is a critical parameter in laser holographic interferometry, laser speckle photography, and holospeckle interferometry. In this paper a statistical analysis for computing the three-dimensional dimension of laser speckle is presented. Explicit formulas have been derived for laser speckle in a free space from a circular scattering area along with some supporting results from an experimental investigation.
