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 fibers for localization (zone identification) of the perturbation, particularly, the present invention relates to a two dimensional array based speckle pattern sensing system having 4×3 (12) multimode fibers for sensing perturbation in multiple zones, said multimode fibers 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.
