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, the factors that result in speckle decorrelation which, in turn, affects the fringe visibility and sets the upper limit of displacement measurement, the new techniques of holospeckle interferometry, real-time and electron microscope speckle photographies and finally the automatic processing of Young's fringes, and digital correlation techniques.
