Paper Abstract

The application of a transportable electronic speckle pattern shearing instrument, based on multiple laser sources is presented. Uniform illumination over a wide surface is assured by inexpensive and multiple laser diodes. High visibility deformation and vibration patterns have been obtained using a modified Michelson interferometer, prisms, and diffractive components as shearing optics.
