Abstract: The double-pulsed speckle interferometry method is very much simpler than the double pulse holographic interferometry and allows a quick analysis of the interferograms without the development of films and hologram reconstructions. It is thus well suited for industrial applications. The system can be extended to determine the three components of the deformation by illuminating the object from three directions and by observing with three cameras. Double-pulsed ESPI can be used to measure rotating objects with an optical derotator which compensates the rotation of the object optically.
