Carrier Phase Shifting

The theory of an automated fringe pattern analysis using the spatial-carrier phase shifting method for moiré interferometry is presented. The automated method is shown to provide a fast and accurate strain measurement over the whole field. Measurements on a brass specimen and a tapered laminated composite specimen are shown to highlight the efficiency and the capability of this technique for moiré interferometry. The filtering technique used to remove noise from the required displacement function is also presented.
