Two multimode silica fibers have been introduced into a tubular furnace while a HeNe laser source was launched into a fiber edge, projecting speckle patterns to a commercial webcam. A computer generated different heating and cooling sweeps while the specklegram evolution was recorded. The achieved results exhibit a remarkably linearity in FSS’s sensitivity for temperatures under 800ºC, following the thermal expansion of fused silica.}, organization = {This work has been supported by the project TEC2013-47264-C2-1-R.}, publisher = {SPIE Society of Photo-Optical Instrumentation Engineers}, publisher = {Proceedings of SPIE, 2015, 9634, 96347J}, publisher = {24th International Conference on Optical Fibre Sensors, Curitiba, Brazil, 2015}, title = {Fiber Specklegram Sensors sensitivities at high temperatures}, author = {Rodríguez Cobo, Luis and Lomer Barboza, Mauro Matías and López Higuera, José Miguel}, }
