Abstract

An automated analysis system is described with subsequent image processing enabling one to analyze complete interferograms. Digital image processing techniques are used to obtain high quality phase maps. Some applications in deformations determination and nondestructive testing (NDT) are given. Phase errors are discussed in some detail.
