Abstract
Official abstract text for this publication.
A bearing comprises a Bragg grated optical fiber to measure one or more parameters of the bearing. The optical fiber is coupled to the bearing in such a way that at least a part of the optical fiber that comprises Bragg grating is curved. The grating which is curved is adapted to the curvature in such a way that the frequency response is well defined and not spread out. This is achieved by arranging the gratings such that even though the fiber is curved the gratings appear to be substantially parallel instead of being influenced by the curvature.
First claim
Opening claim text (preview).
The invention claimed is: 1. A bearing comprising a Bragg grated optical fiber for measuring one or more parameters of the bearing, the Bragg grated optical fiber attached to the bearing such that a grating of the optical fiber is curved, and wherein the grating of the Bragg grated optical fiber is adapted to the curvature in such a way that the influence on the frequency response due to the curvature is minimized. 2. The bearing according to claim 1 , wherein…
