Abstract: 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.

The light guide has elongated shape and is configured to guide an incident light in a propagating direction. The light guide includes a core and a cladding disposed around the core. The first grating is disposed in a boundary area, the boundary area including an outer surface of the core, and an adjacent area that is adjacent to the outer surface. The first grating includes a first periodic structure along the propagating direction with a first pitch, and is configured to generate a first diffracted light from the incident light. The light detector is configured to detect the first diffracted light from the first grating, and detect a bending of the light guide based upon an optical feature amount of the first diffracted light.

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.

Abstract: An insertion module inserted into inside of an observed object includes a light-source light emitting module, around its distal end, configured to emitted light from a light source and a detector, provided close to the distal end, configured to detect a light quantity of incident visible light. A controller controls the light source such that a null signal is transmitted from the light-source light emitting module, the null signal being characteristic for detection of the position of the distal end and obtained by making at least light of a predetermined wavelength region have an absence of visible light. The detector performs detecting operation in a period in which the null signal is transmitted. A determination module performs determination relating to the position of the distal end, based on detection information outputted by the detector.
