“…In the foregoing discussion it was assumed that the emulsion has a linear response range and that the holograms were recorded on the linear range. We point out that the majority of tests were done with a solution physical developer [9], which has an extremely wide dynamic range, several others of magnitude of exposure energy. Further tests are required on other types of developer; however, as we apply a contrast bias, and the contrast variations are around this bias value, any developer ought to give comparable results.…”

A new technique capable of obtaining quantitative values of the rotation angle of the polarization vector by using holography is presented. This is a two-stage holographic process; during the recording stage a hologram of the object of interest is obtained. The reference beam is composed of two beams that form a small angle between them and keep their polarization states at right angles to each other. In the reconstruction stage of the hologram, two images from the hologram are obtained along two different angles. As a result of the interference between these two images, a set of parallel fringes is formed at the image plane. The fringe contrast on the reconstruction is related to the angle of the polarization vector of the light at each position on the image plane. Measurements of the rotation of the polarization angle of a fraction of a degree were obtained. The main application of this technique is in the study of transient phenomena, where single-shot measurements are the only means of obtaining reliable data.
