Abstract

A novel polarization-maintaining fiber sensor based on magneto-optical modulation for transverse stress measurement is proposed. The composition of the sensor system is introduced in detail. Polarized light is used as the stress information carrier, and magneto-optical modulation is used to improve the anti-interference and sensitivity of the system. According to the light phase change caused by the elastic optical effect, the theoretical relationship between the azimuth angle and the transverse pressure is derived in detail through the change of the Jones matrix. The technology extends the new measurement method of polarization-maintaining fiber in the sensor field and has certain reference value in the field of micro-pressure measurement.
