Abstract
Basic principles and advances of the laser speckle strain gauge are described which optoelectronically detects speckle displacements caused by deformation of a diffuse surface and separates strain by means of differential optical systems. It is a perfectly non-contacting and automatic method. Several problems for practical application of the gauge are presented together with proposals for solving them.
