Abstract
A high-precision temperature-controlled narrow band-stop fiber Bragg grating
(FBG) filter and light source self-calibration technique are proposed for
application in the Brillouin optical time domain reflectometer (BOTDR) sensor
system. With the proposed application, the BOTDR sensor system maintains good
long-term stability and temperature precision through the reduction of the center
wavelength drift in the FBG filters and corresponding decrease in the changes in
light intensity. The experiment result shows that temperature precision of 1
°C and temperature stability of 0.7 °C can be achieved in a
temperature sensor over a range of 8 km.
