On Speckle Diffraction Interferometry for Measuring Whole Field Displacements and Strains

Abstract

The procedure for using laser speckle diffraction interferometry to measure small displacements and strains is described. The variation of basic experimental parameters is investigated. A typical application of the method is discussed and data is presented for the displacement distribution around an interference fit fastener.
