Simultaneous recovery of strain and temperature fields by the use of two-moded polarimetry with an in-line mode splitter/analyzer.
We report the simultaneous recovery of temperature and strain through measurement of polarization changes in the LP(01) and LP(11) modes of Andrew Corporation elliptical-core fiber. This technique required the development of an in-line mode splittery/analyzer, which is also described. The scheme has been demonstrated to be sensitive to changes of 1 degrees C and 5 microepsilon and is compatible with white-light multiplexing methods to provide quasidistributed information.
