Abstract

The basic principles of digital shearography or shear speckle interferometry and examples of
the application of modern methods of digital shearography are considered. Experiments on
obtaining shearograms with various configurations of optical elements using a Fresnel
biprism and a Michelson interferometer have been carried out. Two variants of the optical
scheme for forming the image shift have been tested. A scheme of a compact speckle
interferometer for digital shearography based on a Michelson interferometer is proposed and implemented. A software algorithm for obtaining shearograms has been implemented. The
device was tested under conditions of sensitivity to out-of-plane deformation on samples of
the type of a round thin membrane. Experiments were carried out to detect defects in
structures and welds by the presence of zones with non-uniform deformation
