Abstract

Three algorithms, namely the Fast Fourier Transform (FFT), Phase Shifting And Logical Moiré (PSALM) and a combined Finite Element Method and Moiré Interferometry (FEMMI), is used to analyse moiré interferometric patterns. The advantages and disadvantages of the method are exposed using the same fringe pattern for analysis.
