Abstract:A simple and accurate method of measurement of absolute retardation using holography is described. In this, the retardation added in the object beam between the exposure causes a shift in the fringe pattern in the reconstruction. This is achieved by rotating the direction of polarization of the beam between the exposures. The method makes use of a single view, and it has some specific advantages over the present methods in vogue. Some experimental results are presented as supporting evidence. The method is use… Show more
