Paper Abstract

High temperature gradient of a conventional tubular furnace is characterized using a single fiber sensing line with wavelength-multiplexed short-length regenerated Fiber Bragg Gratings. The multiplexed gratings are simultaneously regenerated using a high temperature annealing process. Temperature calibration from ambient temperature up to 850°C is conducted leading to a standard deviation of 0.33°C after polynomial fitting of the wavelength shift with temperature.
