Paper Abstract

A new polarimetric fiber-optic sensor with passive and remote sensing head has been introduced. The pseudo-heterodyne detection is applied for the sensor work. The modulation of phase difference of the fiber modes is induced due to change the fiber birefringence with the help of axial strain or lateral pressure. The sensor resolution can potentially reach the resolution of two-fiber interferometers. The sensor scheme is free from some drawbacks are specific to two-fiber interferometric sensors. The sensor can be utilized as vibrometer, acoustic sensor, accelerometer, etc., according to construction of the sensing head.
