Abstract :
In this paper an optical scheme and the operation principle of strain sensor based on multimode polymer optical fiber is investigated. The possibility of measuring of the relative strain by processing of speckle patterns at the exit face of multimode fiber is studied theoretically and experimentally. The algorithm of correlation processing of speckle pattern is developed too.
