High-Precision Endoscopic Shape Sensing Using Two Calibrated Outer Cores of MC-FBG Array

2025-12-24

Abstract excerpt

We presented a high-precision endoscopic shape sensing method using only two calibrated outer cores of a multicore fiber Bragg grating (MC-FBG) array. By leveraging the geometric relationship between two non-collinear outer cores and the central core, the approach determines curvature and bending angle without multiple outer-core measurements, reducing computational complexity and error propagation. Experimental r...
