This paper presents the results of thermal tests performed with commercial optical fiber Bragg grating (FBG) temperature sensors and raw FBGs fabricated by Photonics Division of IEAv. Test results show significant differences on dynamic response behavior among all sensors and gratings under fast variations of environmental temperature. This effect may suggest a limitation on the use of sensors based on this technique in applications requiring fast and precise response.
