Abstract
A device and system for enabling calibration of a structure includes at least one elongate strap having a lower temperature coefficient than the structure, and a length sufficient to encompass a circumference of an external surface of the structure, and at least one diffraction grating having a temperature coefficient at least as high as the structure, wherein the diffraction grating is coupled to the strap and is in direct contact with the external surface of the structure. Deformations in the external surface of the structure induce corresponding deformations in the diffraction grating.
