Abstract
Difference holographic interferometry (DHI) can be used for direct opt ical comparison of two nominally identical objects (master and test) a nd gives the results of the comparison in the form of an interference pattern displaying the difference in deformation, shape, or refractive index distribution change of the two objects. The concept of the DHI is discussed and the main techniques and typical applications are pres ented. Finally, theory is briefly overviewed.
