| Abstract: | Temperature calibration in a distributed optical fiber temperature sensor system based on Raman back scattering was discussed. A very useful principle was presented on the basis of considering system stability and system temperature sensing accuracy. By measuring and studying the loss due to status and radius differences of the reference optical fiber, a solution on how to carry out calibration was also described. Experimentations indicated that not only the principle is reasonable and correct, but also it is helpful to the design of such a system. |
