We present, for the first time to our knowledge, a dual strain/temperature sapphire fiber Bragg grating sensor. Temperature and strain coefficients of the grating are evaluated. By recording the blackbody radiation level above 650 degrees C, wavelength shifts due to temperature can be decoupled from those due to strain.
我们首次提出了一种双应变/温度蓝宝石光纤布拉格光栅传感器。评估了光栅的温度和应变系数。通过记录 650°C 以上的黑体辐射水平，可以将由于温度引起的波长位移与由于应变引起的波长位移解耦。
