Abstract:
An optical bend measurement apparatus includes a light source unit configured to supply measurement light, an optical transmission body configured to transmit the measurement light, a optical characteristic change members provided in different portions of the optical transmission body, and a photodetection unit configured to detect light output from the optical transmission body. Each optical characteristic change member imposes a change of optical characteristics on light impinging on the optical characteristic change member depending on a bend quantity in a specific direction of a portion of the optical transmission body where the optical characteristic change member is provided. The photodetection unit separates and detects the light that has undergone the change of the optical characteristics to independently measure bend quantities in specific directions of the different portions of the optical transmission bodies based on intensities of the detected light.
