Abstract

We describe a robust system to retrieve the phase using a temporal phase unwrapping approach. Combining the polarization Michelson interferometer with a polarizing sensor and temporal phase unwrapping algorithms the phase unwrapping procedure is not only simplified, but also the computing time is reduced one order of magnitude compared with other algorithms and we can analyze dynamic events in real-time, i.e., 7.4fps. In the approach taken, each pixel is processed independently obtaining the phase difference for a specific time opening the possibility of real-time analysis and the masking process is avoided limiting the noise propagation in spatial manner. Validation experiments are presented.
