The interferometer presented in this report is based on a holographic Mach-Zehnder's interferometer designed for visualization of phase nonhomogenities of transparent objects. It is an interferometer using a TV camera and a digital image processing system. Interferograms are obtained by subtraction of the finite fringe quasi holograms, and therefore there is no ambiguity in the interpretation of the direction of the refractive index gradient.
