Abstract
Basic principles and advances of the laser speckle strain gauge are described. The gauge optoelectronically detects speckle displacements caused by deformation of a diffuse surface and separates strain by means of a differential optical system. The method is noncontacting and automatic. Several problems for practical application of the gauge are presented, together with proposals for solving them.
