摘要
Fringe patterns with a multiplicative phase shift among them appear in experimental techniques as photoelasticity and RGB shadow moire, among others. These patterns cannot be processed using standard phase-shifting demodulation techniques. In this work, we propose to use a multiframe regularized optical flow algorithm to obtain the interesting modulating phase. The proposed technique has been applied to simulated and experimental interferograms obtaining satisfactory results.
