SHAPE SENSOR AND TUBULAR INSERTION SYSTEM |
摘要 |
A shape sensor comprises a shape sensor main body which comprises an optical fiber capable, a detection object section, and a light detecting section to detect the detection light and which is capable of measuring a shape of a measurement target object by utilizing a change in characteristics of the light detected through the detection object section in accordance with a change in curvature of the optical fiber when the optical fiber curves; and a curving direction regulating section which is provided on at least a part of the optical fiber along an optical axis thereof and regulates a curvable direction of the optical fiber to a desired direction; wherein the curving direction regulating section is a core member which is disposed in at least a part of the shape sensor main body along the light propagating direction of the optical fiber and whose main curving direction is regulated. |

1. A shape sensor comprising:
a shape sensor main body which comprises a light source, an optical fiber configured to propagate desired detection light emitted from the light source, a detection object section arranged in a part of the optical fiber, and a light detecting section to detect the detection light propagated through the optical fiber and which is configured to measure a shape of a measurement target object by utilizing a change in characteristics of the light detected through the detection object section in accordance with a change in curvature of the optical fiber when the optical fiber curves, and a curving direction regulating section which is provided on at least a part of the optical fiber along an optical axis thereof and regulates a curvable direction of the optical fiber to a desired direction, wherein the curving direction regulating section is a core member which is disposed in at least a part of the shape sensor main body along the light propagating direction of the optical fiber and whose main curving direction is regulated. |
