Paper Abstract

A polarimetric DBR fiber laser sensor array for simultaneous measurement of liquid level and temperature has been proposed and experimentally demonstrated. Operation principle of the proposed DBR fiber laser sensor has been theoretically analyzed. Based on beat frequency/wavelength hybrid interrogation, discrimination between liquid level and temperature has been achieved. Furthermore, three fiber laser sensors were cascaded to build up a serially multiplexed sensor array, showing a good multiplexing capability for potential network applications.
