In this work, the possibility of using the inherent lateral chromatic aberration (LCA) of the lenses to calculate the phase of fringe patterns is reported. It is shown that a single fringe pattern can be decomposed into three phase shifted images and that the phase can be retrieved successfully from those images. Experiments are carried out to retrieve the phase of some fringes, and the results are compared with those obtained using standard temporal and spatial phase shifting algorithms.
