The analysis of holointerferograms is hindered by the fact that they by themselves do not contain sufficient information to determine the sign of the phase change in the pattern. Various techniques have been proposed to resolve this sign ambiguity e.g. the introduction of a carrier fringe pattern, sandwich holograms and the use of multiple reference beams from different directions. This thesis attempts to utilize the carrier fringe method along with image processing techniques to obtain a quantitative idea of the deformation of the surface of an object. The merits and demerits of this technique are discussed and it is applied to a practical case.
