Abstract
A sensor system for sensing a measurand field within an environment includes an optical source, such as a light emitting diode, for providing broadband light to an array of serially coupled sensor elements disposed within an optical fiber (28). Each sensor element includes a fiber grating (Bragg grating) (44) which, when illuminated, reflects a narrow band of light having a specified central wavelength. The optical fiber is deployed in a high strength hermetically sealed capillary tubing structure (5). Within the capillary tube, at least in the area of the sensor elements, the capillary tubing is filled with a high-density, low-compressibility, and high thermal conductivity material, such as a liquid (48), which completely fills all of the void spaces within the capillary tubing between the tubing and the sensor elements such that compressive forces which are exerted on the extermal surfaces of the tubing are accurately transmitted to the sensor elements.
