Paper Abstract

Commercial FBGs (Fiber Bragg Gratings) are used to measure temperature gradients. The measurement system is based on an electronically tuned solidstate laser, S-TLD. Calibration is carried out using a dual Peltier water-cooled system. Spectral parameters are extracted from reflection spectra using LabView software. A 'Look-Up Table' approach is used as a means of solving the inverse scatter problem.
