Abstract:
A light source device includes a first excitation light source which emits first excitation light having a wavelength in a first wavelength region, a first optical member, a second optical member and a holding member which holds the first optical member and the second optical member. The first optical member converts at least part of the first excitation light to emit first wavelength converted light, and increase divergence angle of the transmitted first excitation light by a first incremental angle. A second optical member is disposed in a region including an optical axis of the first excitation light, and increases the divergence angle of the transmitted first excitation light by a second incremental angle larger than the first incremental angle.

A curvature sensor includes a light source, a flexible light guide including cores, and FBG sensors that are provided in the cores and constitute FBG sensor groups at predetermined positions at predetermined positions along longitudinal axes of the cores. The curvature sensor includes a detector that detects an optical spectrum of light from the FBG sensors, and a processor that obtains a bend of the light guide. FBG sensors provided in a core include a first FBG sensor and a second FBG sensor next to it. The first and second FBG sensors include gratings having first and second pitches. The first pitch is shorter than the second pitch and is closer to the second pitch than other pitches of gratings of all FBG sensors that are provided in the core and include gratings having pitches shorter than the second pitch.
Abstract:
A supporting apparatus for supporting insertion of a flexible insertion member into a subject and removal of the insertion member includes a position acquisition unit, an interrelation calculation unit and a determination unit. The position acquisition unit acquires information on displacements at at least two attention points located at positions that are different in the longitudinal direction of the insertion member. The interrelation calculation unit calculates a degree of interrelation of the displacements acquired at the at least two attention points. The determination unit determines a state of the insertion member or a state of a predetermined target portion of the subject, based on the degree of interrelation.
Abstract:
A supporting apparatus for supporting insertion of a flexible insertion member is provided. In the supporting apparatus, an attention point acquisition unit specifies a first attention point specified by a shape of the insertion member. A first displacement acquisition unit acquires a first displacement, which is a positional change of the first attention point. A second displacement acquisition unit acquires a second displacement of a second attention point. A displacement information calculation unit compares the first displacement of the first attention point and the second displacement of the second attention point with each other and calculates displacement information. A determination unit determines state of the insertion member or the subject, based on the displacement information.
Abstract:
An illumination apparatus includes at least one laser diode, an illumination section, and a light control circuit. The illumination section uses light emitted from the laser diode as illumination light. The light control circuit controls light intensity of the laser diode by pulse-modulating a drive current supplied to the laser diode. The light control circuit controls the light intensity of the laser diode in combination with a duty ratio and a peak current of the pulse-modulated pulse drive current in combination in a multi-oscillation mode region in which a wavelength spectrum width of the light emitted from the laser diode is equal to or larger than a threshold wavelength width.
