Paper Abstract

We deal with a novel proposal to obtain the curvature fringes by a quasi-real time technique incorporating the developed optodigital system for curvature measurement. An asymmetric Gaussian filter centered on the central frequency of the curvature fringes isolates the curvature fringes from the carrier shear fringes
