Digital Moire Interferometry (DMI)—a low cost and sufficiently sensitive geometric interference technique with very low stability requirement analyzed through digital image processing, has been applied to compressible conical flows. An inverse Abel transform algorithm for image reconstruction from moire deflectograms has been developed.
