High-temperature multiparameter sensor based on sapphire fiber Bragg gratings.

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.
