Abstract

Thermal radiation that is present when sapphire fiber Bragg grating sensors are operated at high temperatures (> 1000 °C) is used to obtain a spectral response of the grating without the use of an external optical source to probe the sensor. Depending on the localization of the heat source, transmission or reflection type grating spectra can be obtained.
