Intrinsic position sensing using optical fiber and coherence domain polarimetry
Detection of the physical position of an object is one of the most important sensing applications in industry and engineering. Not only is the gauging of physical dimensions with such position sensor systems important in its own right, but the monitoring of many operational and control parameters in engineering applications can also be converted into position sensing by use of various transducer systems.
