| Abstract: | In this paper two-reference-beam holo-speckle interferometry has been analysed in detail by means of statistical optics. The relationships among the average density distributions of holographic and speckle interference fields over a local area, the parameters of optical system and the components of a 3-D deformation field are obtained. The lower and upper limits of the measurement of out-of-plane and in-plane displacement are discussed. Finally, some experimental results are given. |
