This type of sensor can measure strain andtemperature simultaneously with merits of low cost, high sensitivityand immunity to electro- magnetic interference. The sensor has anaccuracy of 20 με and 0.8 deg.C over a strain range of 500～1 500 με and a temperature range of 5～36 deg.C under experimentalconditions.展开更多
文摘A novel and simple fiber grating sensor based on high-duty-cyclesample fiber bragg grating is proposed and demonstratedexperimentally. This type of sensor can measure strain andtemperature simultaneously with merits of low cost, high sensitivityand immunity to electro- magnetic interference. The sensor has anaccuracy of 20 με and 0.8 deg.C over a strain range of 500～1 500 με and a temperature range of 5～36 deg.C under experimentalconditions.
