Abstract

Major advances in using coherent and incoherent speckle patterns for displacement and strain measurements are reviewed. Topics include the laws of spatial movement of laser speckle, the halo functions of coherent and incoherent speckle patterns, decorrelation factors and their effect on the fringe visibility and the upper limit of measurement, new techniques of holospeckle interferometry, real-time and electron microscopic speckle photographies, and the automatic processing of Young's fringes.
