Abstract
Fringe phase is detectable from one-shot image in color fringe projection, since three-primary-colors intensity information can be used from an image independently. Measurement of dynamic deforming object is carried out by using this method. Vibration mode analysis is performed by the time-average method of projected monochromatic grating pattern, which is similar to holographic interferometry. However it is difficult to analyze sub-fringe by those techniques because only a vibrating fringe pattern is captured. Hue information of time-averaged color fringe is applied in this experiment to analyze the fringe phase precisely. Proposed method where the hue of projected fringe is modified by oscillation is compared with ordinary technique where the fringe intensity is modified.
