Three-dimensional dimension of laser speckle
Applied Optics, 1992It 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.

A technique is presented to determine surface contours of 3-D objects by laser speckle interferometry. A double exposure specklegram is recorded by giving the object a small tilt between exposures. Surface contours are obtained by Fourier filtering of the specklegram.

We demonstrate experimentally that the intensity correlation function with shift in the scattered wave vector or with identical shifts in both the incident and scattered wave vectors form Fourier transform pairs, respectively, with the intensity distribution on the output surface and the propagator between the input and output surfaces.

We report on a new laser feedback mechanism that uses speckle-pattern phenomena to create highly dispersive feedback. This speckle mirror is capable of creating laser emission as narrow as that from laser cavities using a number of dispersive elements such as gratings and prisms.
