Abstract
Official abstract text for this publication.
A bearing comprises a Bragg grated optical fiber to measure one or more parameters of the bearing such as load, temperature, acceleration/vibration and identification. To be able to fit as many Bragg gratings as possible, the utilization of the corresponding frequency plane output is optimized by having low bandwidth next to large bandwidth sensors in the frequency place. The corresponding physical sensors such as load sensors on a bearing will not be adjacent. Sensors in the loaded zone are giving a high bandwidth output and sensors in the un-loaded zone are giving a low bandwidth output, thus even though these are not physically adjacent, the corresponding frequency areas are adjacent by appropriate grating.
First claim
Opening claim text (preview).
The invention claimed is: 1. A bearing comprising a Bragg grated optical fiber having a plurality of grated areas, each grated area corresponding to a different area in a frequency plane, wherein each grated area is grated such that physically sequentially adjacent grated areas correspond to frequency areas that are separated in the frequency plane, and wherein a physical sequence of Bragg grated areas is different to a sequence of corresponding frequency areas in the frequency pla…
