摘要： Sensing parts are formed in different directions in a circumferential direction in substantially a same position in the longitudinal direction thereof. Each sensing part is configured to include an optical characteristic changing member which generates the optical signals having absorption wavelength characteristic regions that vary from sensing part to sensing part by giving an optical characteristic change, which differs from that of other sensing parts, to the sensor light incident thereon in accordance with an amount of bending in a specific direction. A light detector detects the optical signals included in sensor light from a light source, which has passed through the sensing parts and undergone the optical characteristic change.

摘要： A curvature sensor is to be mounted along detection target to allow a curvature of the detection target. The sensor includes a light source, a light guide to guide light from the light source and sensing parts having light absorbability. The sensing parts include absorption bands having different intrinsic absorption patterns and characteristic absorption bands having intrinsic characteristic absorption patterns in the absorption bands. A light detector allows residual light not absorbed by the characteristic absorption bands to be detected, the residual light being included in light of bands corresponding to the characteristic absorption bands and radiated to the sensing parts from the light source. A calculator computes a curvature of the detection target based on a rate of change in the residual light.

摘要： An insertion shape detection apparatus includes an insert portion having flexibility. The insert portion includes a shape estimation section where curved shape is estimated and a shape non-estimation section where curved shape is not estimated. The insertion shape detection apparatus includes a sensing part arranged only in the shape estimation section to detect the curved shape of the shape estimation section. Thus, the number of sensing parts is reduced and the increase in the diameter of the insert portion and complicated processing of curve information is avoided, while the curved shape of the insert portion in a section necessary to assist an endoscopic observation can be detected.

摘要： A bend information computation apparatus includes a generation unit and a bend information arithmetic operator. The generation unit generates suppression information that suppresses first information representing a variation in spectrum not derived from a bend of a detection target provided in a light guide on the basis of light source spectrum information. The bend information arithmetic operator operates second information representing a variation in spectrum derived from the bend on the basis of a spectrum of light guided by the light guide, operates third information representing a variation in spectrum derived only from the bend on the basis of the second information and the suppression information, and operates bend information on the basis of the third information.
