A simple fiber optic displacement sensor (FODS) is proposed and demonstrated for angle measurement. The proposed sensor utilizes a multimode fused coupler as a probe as well as a flat or concave mirror as the target. For the flat mirror, the highest sensitivity and the best resolution is obtained at...
