Comparative Phase-Shifting Digital Speckle Pattern Interferometry Using Single Reference Beam Technique
Abstract
This paper reports on the application of phase shifting interferometry to digital speckle interferometry.The method here enables the measurement of phase distributions corresponding to the difference in displacements of two nominally identical specimens subjected to similar common rotation steps.The method is investigated, and its viability is demonstrated by experimental results.
