Paper Abstract

Shape measurement and strain distribution measurement are important to analyze the behavior of a moving object. In this paper, a dynamic shape and strain measurement system by the sampling moire method is developed. Recently, phase analysis method using phase-shifting moire patterns generated in a computer from a grating image is proposed. This method is very suitable for dynamic measurement because the phase can be obtained from a one-dimensional or two-dimensional (2-D) grating image with high accuracy. It is possible to analyze strain distribution and shape measurement of a moving object using a grating pattern attached on the specimen surface. A dynamic shape and strain measurement system by the sampling moire method is developed. The principle and experimental results applied to a rotating object are shown.
