Abstract

The problem of quantification of holographic interferograms is not trivial. Even today, 20 years after the invention of hologram interferometry, there is not yet a general method available that can be used reliably to interpret holographic fringe patterns to obtain information on displacements and/or deformations of arbitrary objects. However, a number of methods and systems have been developed for specific applications. The results that are being obtained using these methods are contributing to the further growth of holographic interferometry; the most promising of the methods used are those allowing automated interpretation of holograms.
