Abstract: Digital shearing speckle interferometry is a laser-based, optical, non-contacting and non-destructive method widely used for the stress and strain analysis of loaded static objects. In this paper, the authors have adapted the technique for whole-field modal analysis. The theoretical basis for this technique is presented and experimental verification is performed on a thin square plate fully constrained and subjected to a steady-state excitation. © 1994.
