Abstract :
This communication reports on a novel intensity-based optical fiber strain sensor. A conventional multimode fiber was drawn-down to give a reduced cross section that resembled a symmetrical taper. The sensors were embedded into glass fiber reinforced epoxy composites and the light transmission characteristics through the profiled optical fiber were measured as a function of applied stress. A linear response was observed.
