OPTICAL FIBRE GRATING SENSOR SYSTEM AND METHOD

摘要

The present invention relates to a kind of fibre optical sensors of optical fiber, including one first grating to be suitable for running first wavelength range; At least one set of further grating is suitable for running second wave length range, and each grating is suitable for running a part of second range; Wherein,Each grating described group opereating specification each other partly at least one other such raster manipulation range. The present invention extends also to a kind of sensing system and method, utilizes this optical fiber.
