Abstract
A temperature sensor array comprises an optical fiber () on which are a plurality of Bragg gratings () on respective spaced apart portions of the fiber. Each portion is in a housing () which freely houses the said portion substantially without axial strain on the fiber within the housing and which also isolates the grating from strain imposed on the fiber outside the housing. Thus substantially only changes in temperature affect the Bragg grating of that portion. The array may be used to detect and control the temperature of a tool () for forming a composite component amongst other uses.
