Abstract:
A curvature sensor includes a light source, a flexible light guide including cores, and FBG sensors that are provided in the cores and constitute FBG sensor groups at predetermined positions at predetermined positions along longitudinal axes of the cores. The curvature sensor includes a detector that detects an optical spectrum of light from the FBG sensors, and a processor that obtains a bend of the light guide. FBG sensors provided in a core include a first FBG sensor and a second FBG sensor next to it. The first and second FBG sensors include gratings having first and second pitches. The first pitch is shorter than the second pitch and is closer to the second pitch than other pitches of gratings of all FBG sensors that are provided in the core and include gratings having pitches shorter than the second pitch.

Claim (Index 15):
The curvature sensor according to  claim 12 , wherein the elongated object has a first portion and a second portion, a bending elastic modulus of the first portion is larger than a bending elastic modulus of the second portion, and in an FBG sensor group corresponding to the first portion, \u0394\u03bbmn/dm is set to be smaller than an FBG sensor group corresponding to the second portion.
