Abstract
A fiber optic temperature sensor, for which the changes in modal biref ringence of a short section of a long birefringent fiber are monitored remotely, is described. It employs a white light interferometer, whic h is formed by two concatenated spiral polarization mode couplers. Ane w method for white light interferometer output signal processing is de scribed which provides a high accuracy absolute temperature measuremen t even in discontinuous operation of the sensor. Experimental results are presented for temperature measurements over a 100 degrees C range with resolution of 3 X 10(-3 degrees)C. (C) 1998 Published by Elsevier Science B.V. AII rights reserved.
