Interferometric Fiber-Optic Sensor Arrays Polarization Control by Summing
A novel method is presented to control the optimum input polarization of the interferometric fiber optic sensor arrays by the sum of each sensor′s feedback signal. The minimum visibility of the element in the array under control is calculated, and the probability to reach this situation is estimated. The analyses show that the method is both simple and feasible. Each sensor′s visibility can approach to 1 by signal process, which eliminates the polarization induced fading in each sensor of the array.
