Statistical analysis of shearing speckle interferometry
The imaging process of shearing speeklegram, its spectrum distribution and formation of gringes created by whole-field filtering are analysed by means of stati-sbioal optics in this paper. We find that the fringe distribution is related not only to the derivation of 3-D displacement but also to the amount of in-plane displacement. Accordingly the factors influencing the quality of fringes are discussed and experimental demonstration is given.
