In contrast to pre¨ious bulk optic approaches, this letter describes a no¨el all-fiber polarimeter for chemical sensing using D-fiber. The polarimeter is a single-fiber sensor, and is less sensiti¨e to en¨ironmental fluctuation in comparison with the two-fiber interferometric sensor. Theoretical sen
## Abstract A simple intensity modulation based displacement sensor using fiber optic coupler probe is proposed and demonstrated for sensing the concentration of alcohol solution. The intensity of light reduces almost linearly with the displacement and the sensitivity of the curve is dependent on t
