Simultaneous Measurement of Humidity and Temperature Based on a Long-Period Fiber Grating Inscribed in Fiber Loop Mirror

A fiber loop mirror sensor with a long period grating (LPG) inscribed in the polarization maintaining fiber (PMF) is proposed and experimentally demonstrated for the measurement of humidity and temperature simultaneously. The LPG is inscribed in the PMF by a CO 2 laser and then connected with a 3-dB...
