We present the development of a single shot interferometric system based on polarization and diffractive elements recovered from spare computers. The use of salvaged lenses, beam splitter cubes and linear polarizers lower the cost of our system in comparison with those already reported. Our system is also capable of dynamic phase measurements with an accuracy comparable to similar implementations with high end manufactured optics. We report here our results obtained from four simultaneous interference patterns. The presented interferometer can be easily implemented for various applications in single shot polarizing phase shifting interferometry.
In this research an interferometric system was developed that generates four simultaneous interferograms with independent phase shifts using modulated polarization. The proposed system consists of three coupled interferometers: the first system is a polarized Mach-Zehnder interferometer, which generates the pattern, the second and the third interferometer system, function as replicators of the first pattern, so the four patterns are generated. To show the novelty of the developed system, the calculation of optical path difference (OPD) for phase samples are shown.
