A method to recover arbitrary temperature profiles along a chirped fibre Bragg grating sensor is presented. We demonstrate a nonlinear lookup table method to recover the shape, width and position of a disturbance in temperature after compensating for distortions in the result of integrating changes in the power reflectance spectrum.
