Paper Abstract

We report on the errors obtained by comparing the in- and out-of-plane displacements calculated from the sensitivity matrix with all its components and when it is considered only the component of the largest contributing of each one of the three interferometers. Divergent illumination is considered in the sensitivity vectors evaluation to measure displacement vector components. This analysis is made for a flat elastic target by using of Electronic Speckle Pattern Interferometry (ESPI).
