摘要： A magnetic field sensor system includes a one-axis magnetic field generator that generates a magnetic field, three or more three-axis magnetic field detectors that detect a magnetic field for each axis and are arranged on a substantially straight line, and a calculator that calculates, from a detection result of the magnetic field, a spatial position or a spatial direction of the one-axis magnetic field generator. The calculator selects two or more three-axis magnetic field detectors, which generate no symmetry of magnetic fields, based on a preset judgment standard of symmetry of magnetic fields, and calculates the spatial position or the spatial direction of the one-axis magnetic field generator, based on detection results of the magnetic field between the selected two or more three-axis magnetic field detectors and the one-axis magnetic field generator.

摘要： 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.
