Polarization diversity detection for fiber interferometers using active feedback control of output polarization-mode selection.
The application of an adaptive polarization diversity detection technique in an interferometric fiber sensor system is described. The approach utilizes feedback control of the polarization modes selected at the sensor output and produces the optimum level of total interference signal while allowing the states of polarization of the light in the signal and reference arms of the interferometer to vary randomly.
