Paper Abstract

Expressions of the maximum displacement measurable by holographic interferometry is presented in the paper. From spectrum analysis of an image-hologram, a model of speckle statistics is established in reconstruction viewing system. The results show that the displacements much larger than the mean size of the speckle at holographic plate or at surface of fringe localization can be obtained by holographic interferometry when the viewing aperture is small enough. Methods of increasing the upper-limit of range are also proposed.
