| Research Abstract |
To develop a sensor that monitors configuration of catheter from the outside of human body, feasibility study was performed for sensors based on multicore-fiber with multiple optical cores. This sensor utilized that power coupling between optical waveguides changes by bending of the waveguides. Theoretical evaluations based on optical-power coupling theory and beam propagation method showed that asymmetric waveguides worked as a optical sensor. It was shown that this device detects both of radii and direction of waveguides' bending.
