摘要：

A ring laser based on a transmission-type fiber bragg grating (FBG)-FabryPerot filter sensor probe is proposed, and ignoring the effect of multilongitudinal modes using a special demodulation method, the new scheme is suitable for long distance sensing. Such a sensing system has been demonstrated in the experiment, and the experimental result shows the minimal temperature sensitivity is about 1 degrees C. (C) 2012 Wiley Periodicals, Inc.
