The continuous phase along row or column of the phase fringe pattern is approximated as a weighted linear combination of linearly independent basis functions such as Fourier basis. The weights are accurately estimated based on a state space analysis using the linear Kalman filter. Simulation and experimental results are provided to substantiate the applicability of the proposed method.phase estimationphase derivative estimationlinearly independent basis functionsstate space analysiskalman filterMeasurement of Displacement and Its Derivatives from a Phase Fringe Patterntext::conference output::conference proceedings::conference paper
