Abstract
Although holo-interferometry has long been recognized for its ability to obtain quantitative measurements of minute surface displacements, it has not yet found widespread practical applications. Part of the reason for this is that variations in the reflectivity of the surface often make analysis of the holo-interferogram impossible or highly problematic. In this paper we investigate a filtering technique which uses separate images of the object and holographic image to compensate for variations in surface reflectivity and non-uniform illuminations. We also examine the application of this technique to a new method of holointerferogram analysis, the inverse cosine method.
