ELECTRONIC SPECKLE INTERFEROMETRY, PHASE-MAPPING, AND NONDESTRUCTIVE TESTING TECHNIQUES APPLIED TO REAL-TIME, THERMAL LOADING

摘要

A digital phase-mapping method has been developed for application in real-time electronic speckle interferometry studies. Its principles and application to a continuously deforming object are described. An efficient digital image-processing algorithm has been developed that permits quantitative interpretation of the resulting phase maps. [References: 13]
