In　this　paper,　a　high　birefringence　loop　mirror　sensing　head　was　introduced,　and　its　temperature,　strain　sensing　properties　with　panda-type　HBFLM　were　analyzed　and　researched　in　experiment.　Experimental　results　showed　that　both　the　temperature　and　strain　sensors　have　high　sensitivity,　linearity.　Its　temperature　sensitivity　reached　1.41　nm/degrees　C,　with　the　sensitivity　linearity　was　up　to　0.99968;　Its　strain　sensitivity　was　0.02362　nm　/mu　epsilon,　when　the　linearity　between　strain　and　wavelength　shifts　was　above　0.99912.　This　panda　HBFLM　temperature　sensor　can　be　widely　used　in　some　industries　requiring　high　sensitivity,　miniaturization　of　structure,　and　stability,　such　as　high　voltage　cables,　oil　temperature　measurement,　and　large　monitoring　structure　fields　such　as　detecting　important　buildings,　bridges,　dams.
