Paper Abstract

The authors develop a special configuration of a digital speckle pattern interferometer using a custom diffractive optical element. The resulting interferometer is sensitive only to the in-plane radial displacement component. The area of interest is double illuminated by light diffracted from a special diffractive optical element in such a way that the interference fringe is not wavelength dependent. The authors present in this paper different strategies for improving image quality of the fringe patterns exploring wavelength and coherence properties. The results of the different approaches are presented and compared.
