note = "Funding Information: For Sample #1, the shape reconstruction error is 0.1-0.2 mm in the case of shapes 1, 2, 3, where the deflection angle of the papillotome tip is less than 45°. With an increase in the deflection angle to 90°, an increase in the error value is observed up to 2.5 mm in the case of shape #4 and 4.8 mm in the case of shape #5 with a deflection angle of 125° (Fig. 1 a), which is associated with the limited spatial resolution of the sensor, determined by the distance between neighboring nodes. As can be seen from Table 1, in the case of Sample #2, the reconstruction error rises with an increase in the curvature of the bend, similarly to the situation with Sample #1, and amounts to 0.8 mm at the maximum deformation of the moving part of the papillotome (shape #6, 7). At the same time, this error decreases to 0.2 mm when the FBG is located in the area of maximum bending (shape #8, see Fig. 1). The deviation from the plane for all shapes for both samples did not exceed 0.4 mm. Thus, when comparing the characteristics of Sample #1 (FBG node interval – 15.4 mm) and Sample #2 (FBG node interval – 10 mm), it can be concluded that at small curvature values, the sensors have comparable recovery errors, while at the increasing curvature, Sample #2, due to the higher spatial resolution, allows reconstruction of the shape with less error (less than 1 mm over 80 mm total length).
