Abstract
The present invention relates to an optical fiber for a fiber optic sensor, comprising a first optical grating adapted to operate over a first range of wavelengths; and at least one set of further gratings adapted to operate over a second range of wavelengths, each grating being adapted to operate over a portion of the second range; wherein, each grating within said set has an operating range that partially overlaps with at least one other such grating operating range. The invention also extends to a sensor system, and method, using such an optical fiber.
