## 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
We studied a fiber-optic temperature sensor based on the interference between LP and LP modes of a circularly symmetric few mode fiber. 01 02 Theoretical analysis predicting the sensitivity of such a sensor is presented; the predictions are in excellent agreement with the experimentally measured v
## Abstract The performance of the fiberβoptic displacement sensor with beamβthrough detection technique is investigated. The effects of lateral and axial displacements on the detected output voltage are investigated for various core's diameters of the sensor. The highest sensitivity is obtained at
