abstract = "A reflection type polarization maintaining optical fiber temperature sensor was designed. The operation principle was introduced and the sensing equation was made. Analysis shows that the propagation loss variety is the main factor which will let the sensing equation parameters change. Compared the sensing equation and the expanded equation, the propagation loss coefficient can be separated with the sensor intrinsical parameters and a simple and practical field calibration method, with which the whole sensing equation parameters can be calibrated when certain temperature at the sensor probe was given, was proposed and the calculation equation was made. An experimental sensor system was built and the calibration experiments were done by change the propagation loss and the date obtained were analyzed and compared with polynomial fitting and model calculating. The result proved the field calibration technology and the sensing temperature precision can be better than ±0.5° before and after calibration.",
