Paper Abstract

We have improved the conventional polarization method used to separate and simultaneously capture the moiré interferometry fringe patterns of the U and V fields. The beamsplitter grating and integrated analyzers in the conventional method are substituted for with a Wollaston prism. The operation of this method is thus simplified and quality of the fringe patterns can be improved. Furthermore, it is easy to implement this technique in compact moiré interferometry system with a minimum of additional components. The key points of operation are stressed and an application of this improved method is presented to show its feasibility. Also, the system error due to the use of this technique is analyzed.
