A MULTI-FIBER OPTIC 2D-ARRAY DEVICE FOR SENSING AND LOCALIZING ENVIRONMENT PERTURBATION USING SPECKLE IMAGE PROCESSING

摘要

System for sensing perturbations in a distributed manner using an array of multimode fibres for localization (zone identification) of the perturbation, particularly, the present invention relates to a two dimensional array based speckle pattern sensing system having 4X3 (12) multimode fibres for sensing perturbation in multiple zones, said multimode fibres are imaged in parallel by a charge coupled device (CCD) camera and their speckle pattern analyzed by a conventional image processing hardware to determine the perturbations.
