CATHETER FOR SENSING SHAPE AND CONTACT FORCE BY USING FBG OPTICAL FIBER AND CATHETER SYSTEM THEREFOR

摘要

The present invention is advantageous in that the shape of the catheter can be sensed by detecting the position of bending of the catheter body, the direction thereof, the angle thereof, and the curvature thereof through a triplet calculation of information regarding three wavelengths that have undergone a transition along respective FBGs provided on three optical cores.
