Abstract

For measuring 3D surface movement by means of Electronic-Speckle-Pattern-Interferometry the decorrelation of the out-of-plane component due to the additional inplane movement must be minimized by a resampling of the speckle images or the calculated phase maps in dependence of the measured inplane movement.
