Paper Abstract

Fringe pattern such as interference fringe or moire fringe have been used widely to measure a surface shape, deformation, displacement and so on without contact. However, quantitative analysis of fringe pattern is not always so easy. In this paper, the authors developed two types of interactive fringe pattern analysis systems. One of them is called RIFRAN I in which image processing technique is applied and sectional shape type model is build up semi-automatically. Another one is called RIFRAN II in which tablet digitizer is provided for input of fringe positions and contour line type model is constructed. Furthermore, 3-D model processing systems are developed for proceeding analysis. Key Words: Fringe pattern, Interactive input, 3-D shape model, Sectional shape, Contour line, Quantitative analysis
