Transparent object Wave-Front Distortion has been measured in a Mach-Zehnder interferometer employing as evaluation tool the Multiplicative Analogical Moire Phase-Shifting Method. The measuring procedure is based on the direct superimposition of a transmission grating with a phase modulated high-frequency Mach-Zehnder spatial carrier. Latter, a set of phase-shifted fringe patterns, provided by low-pass filtering of the obtained multiplicative moire patterns, is combined in a Generic Phase-Shifting Algorithm (GPSA). The interesting information is achieved once the previous procedure is carried out with and without the transparent object located at the measuring area. The Wave- Front Distortion can be calculated by subtraction of these results provided by the GPSA or directly if a Differential PSA is employed. A comparison of the results obtained with both algorithms has been done.
