We demonstrate an interferometric fiber-optic bending/micro-displacementsensor based on a plastic dual-core fiber with one end coated with a silvermirror. The two fiber cores are first excited with the same laser beam, thelight in each core is then back-reflected at the mirror-coated fiber-end, and,finally, the light from the two cores is made to interfere at the coupling end.Bending of the fiber leads to shifting interference fringes that can beinterrogated with a slit and a single photodetector. We find experimentallythat the resolution of our bending sensor is ~3x10-4 m-1 for sensing of bendingcurvature, as well as ~70 nm for sensing of displacement of the fiber tip. Wedemonstrate operation of our sensor using two examples. One is weighting of theindividual micro-crystals of salt, while the other one is monitoring dynamicsof isopropanol evaporation.
