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 1):
A curvature sensor comprising:\n a light source that emits light; a flexible light guide including cores that are disposed so as to maintain relative spaces and guide light emitted from the light source; FBG sensors that are provided in the respective cores of the light guide and constitute FBG sensor groups at predetermined positions along longitudinal axes of the cores, respectively, each FBG sensor including a grating having a predetermined pitch and reflecting light with a particular wavelength corresponding to the pitch in light guided by the cores; a detector that detects information on an optical spectrum of light reflected by the FBG sensors or light passing through the FBG sensors; and a processor that obtains a bend of the light guide based on the information on the optical spectrum, FBG sensors that are provided in a core including a first FBG sensor and a second FBG sensor that is provided next to the first FBG sensor along a longitudinal axis of the core, the first FBG sensor including a first grating having a first pitch, the second FBG sensor including a second grating having a second pitch, the first pitch being shorter than the second pitch, the first pitch being closer to the second pitch than other pitches of gratings in all FBG sensors that are provided in the core and include gratings having pitches shorter than the second pitch.
