Abstract:
We present a fiber sensor scheme for discriminative measurement of temperature and strain by space division multiplexing high-birefringence-fiber loop mirrors (HBFLMs). Discriminative measurement of temperature and strain can be realized by sequentially measuring the resonance wavelength shifts of two HBFLMs constructed with the same high-birefringence fiber. Experimental results show that the temperature and strain resolutions reach +/-0.5 degrees C and +/-10 microepsilon, respectively. This scheme can provide not only high resolutions in temperature and strain but also has potential applications in distributed HBFLM sensing.
