Paper Abstract

The portable, grating interferometer for automatic u- and v- displacement measurements is presented. The interferometer modifications, including registration of interferograms by CCD camera and implementing the phase shifting device, are described. The method for fringe pattern analysis using video recorder and spatial carrier phase stepping algorithm is introduced and discussed. The examples of modified interferometer application in fracture mechanics are given.
