Abstract

The linearized perturbation method for fringe pattern analysis and its extension to multifringe analysis have been recently introduced @Hilaire, Ph.D. dissertation ~Rensselaer Polytechnic Institute, Troy, N.Y., 1993!#. For isolating the error component that is due to information processing—as opposed to imageacquisition errors— experimental calibration experiments were conducted by use of computer-generated fringe patterns. The effects of noise, fringe completeness, image resolution, illumination, quantization, and displacement magnitude are tested and discussed in evaluating the software’s performance and accuracy. © 1997 Optical Society of America
