Polarization multiplexing techniques in optical testing

In this investigation, a polarization multiplexing technique is applied to optical testing, especially shearing interferometers, low coherence interferometers and a clocking motion interpreter. Polarization multiplexing techniques possess the snapshot capability in interferometers and polarization imaging devices, and can enhance the measurement speed compared to the conventional optical techniques, which needs a timely-mannered procedure. Experimental results show the various application of the polarization multiplexing technique and give some insight to be used in optical testing area.
