Apparatus for pressure sensing |
摘要 |
The present invention provides an apparatus for distributed pressure sensing. The apparatus comprises a series of Bragg gratings, a light guide incorporating the series of Bragg gratings and a plurality of moveable wall portions. The moveable wall portions are coupled to respective Bragg gratings so that the movement of one of the moveable wall portion causes a force on the respective Bragg grating resulting in a change in strain of the respective Bragg grating. The apparatus also comprises at least one rigid member that is attached at attachment regions between which a sensing region of at least one Bragg grating is defined. The rigid member is arranged so that a strain in the sensing region is not directly influenced by a change in strain of the light guide outside the sensing region.
