We report a novel technique for estimating spatially distributed temperature profile, with a linearly chirped fiber Bragg grating (LCFBG) fiber-optic sensor, and its application in laser ablation of tissue. Our algorithm determines the temperature profile from LCFBG optical spectrum with sub-0.1mm resolution; a spectral flattening filter compensates for LCFBG spectral ripples, allowing operation with commercial gratings. A preliminary experimental analysis on LCFBG monitoring laser ablation of porcine liver has been carried out. © 2016 IEEE.
