In shape sensing, how is the precise 120-degree angular spacing of multiple fibers maintained within the tube?
The OFSCN® Fiber Bragg Grating Shape Sensor is specifically engineered to maintain precise angular spacing of multiple fibers within its structure. The default configuration utilizes three Fiber Bragg Grating (FBG) strings, positioned longitudinally along the sensor’s base material with a fixed 120-degree angular interval between them. This precise arrangement is integral to the sensor’s ability to accurately determine shape and curvature.
