摘要：

We present here a different and modified configuration in order to obtain the curvature fringes by incorporating phase shifting and image processing techniques. Optical fibers are used for obtaining shear fringes in which we have used Wollaston prism as the shear element. (C) 1999 Elsevier Science Ltd. All rights reserved.
