Image Processing Techniques For Fringe Pattern Analysis
G. T. Reid · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1989
Automatic fringe pattern analysis is now used, with appropriate interferometers, in areas such as optical testing, flow visualisation, nondestructive testing, industrial inspection and medical imaging. This paper describes a cross section of the image processing techniques which can be used as the building blocks for an automatic fringe analysis system. The paper uses simple, non-mathematical, descriptions of the various techniques in an attempt to appeal to first time users of the technology.
