Abstract
The theory of an automated fringe-pattern analysis using temporal phas e stepping method for moire interferometry is presented. The automated method provides a fast and accurate strain measurement for moire inte rferometry. Measurements on a tapered composite specimen with a droppe d ply are shown to highlight the capability of this technique to obtai n the strain distribution, particularly around the region with a dropp ed ply.
