| Abstract(in English) | In order to investigate possibility of utilizing speckle patterns to be observed in an output light spot from an optical fiber due to external disturbance for sensing application, a certain load was applied onto an optical fiber through which laser beams emitted from a laser diode were propagating, and changes in speckle patterns in the output light spot from the optical fiber were observed. As a result, when load was applied onto the optical fiber via a flat plate placed over the fiber, no significant changes were recognized in the speckle pattern. On the other hand, in the case where the optical fiber was placed so that corrugated bending of the fiber was induced by the load application, it was observed that the number of speckles in the pattern decreased upon load application onto the optical fiber. |
