Paper Abstract

The actual engineering structures always possess the problems of large dimension, wide range of deformation, complex dynamic response and so on. Therefore, the practical applications of speckle techniques for actual engineering structures encounter some difficulties. Some new attempts have been made to resolve those problems by authors, and main achievements is reviewed in this paper. The focusing principle, evaluating equations and the experimental technique of the oblique-optic--axis speckle photography are presented.The stroboscopic laser speckle photography used for modal analysis, and the electronic speckle pattern interferometry applied to the measurement of the elastic-plastic deformation feild near the crack tip are introduced as well.
