Abstract

As polarization-induced fading is commonly exists in interferometric fiber-optic sensors and their arrays. This paper proposed a method for input polarization control in interferometric fiber-optic sensor arrays. Here, the signal used to control the input polarization state of the multiplexing system is the weighted sum of each sensor's feedback signal for its optimum input control. The suitable feedback signal in a single fiber-optic sensor is presented, and the feasibility for arrays' input polarization control is discussed. The theoretical result of the lowest control visibility is approximate to the ideal value of sin[(pi) /(2N+2)].
