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 ° C and ± 10 μ ε , respectively. This scheme can provide not only high resolutions in temperature and strain but also has potential applications in distributed HBFLM sensing.
