摘要：

An application of a polarization-maintaining photonic crystal fiber (PM-PCF) for torsion sensing is proposed and experimentally demonstrated. The response of the sensor is theoretically validated using the Jones matrix. High normalized sensitivity of similar to 0.014/degrees was measured within a linear twist angle range from 30 degrees to 70 degrees. The sensor response was observed to be highly repeatable over a 90 degrees twist in both the clockwise and counterclockwise directions. The proposed sensor exhibits reduced temperature sensitivity due to the low thermal coefficient of PM-PCF, making it an ideal candidate for torsion sensing.(C) 2010 Optical Society of America
