Abstract: A light radiating unit provided at a distal end portion of an optical fiber includes a first light radiating unit having a predetermined length in a longitudinal direction and capable of radiating therapeutic light having first intensity and a second light radiating unit connected consecutively to the first light radiating unit in the longitudinal direction and configured to radiate therapeutic light having second intensity lower than the first intensity. Consequently, even when a bladder, which is a hollow organ, and a urethra, which is a conduit, are irradiated with the therapeutic light at a time, intensity of the therapeutic light with which surfaces (inner wall surfaces) of respective parts are irradiated is equalized.

Abstract: An endoscope system according to the present invention includes: an illumination unit that radiates illumination light onto a subject, the illumination light having a spatially non-uniform intensity distribution including a light section and a dark section in a beam cross section orthogonal to an optical axis; an imaging unit that images an illumination image of the subject irradiated with the illumination light; and a separation processor that generates two separate images from the illumination image. Among intensity values of pixels within the illumination image respectively corresponding to the light section, the dark section, and a section having intermediate intensity between the light section and the dark section, the separation processor generates the two separate images based on at least two of the intensity values.

Abstract: An interference fringe generating optical system generates an interference fringe, and a magnifying optical system magnifies the interference fringe and projects the interference fringe on an object surface. The magnifying optical system includes an incident-side lens group on the side where a light beam forming the interference fringe is incident and an exit-side lens group on the side where the light beam is emitted and the interference fringe is projected towards the object surface. The expression f1/f2>3 holds, where f1 is the focal length of the incident-side lens group, and f2 is the focal length of the exit-side lens group. The incident-side and exit-side lens groups each have a positive refractive power. The expression xd/(f1+f2)

Abstract: A measurement probe is configured to be detachably connected to a bio-optical measurement apparatus and includes: an illuminating fiber configured to irradiate body tissues with illumination light; light receiving fibers configured to receive return light of the illumination light reflected and/or scattered from the body tissues; an optical element configured to transmit the illumination light and the return light and to keep distances between the body tissues and distal ends of the illuminating fiber and the light receiving fibers, constant; and a contact detecting fiber configured to receive the return light to detect contact between a distal end face of the optical element and the body tissues, and detect the return light at a detection region on the distal end face through which the illumination light and the return light pass. The detection region is located outside an illumination region of the illuminating fiber.

Abstract: An optical unit for a wavelength-selecting switch according to the present invention comprises: an input port; a dispersion section that produces wavelength dispersion of input light that is input from the input port; a light-collecting element that collects the light dispersed by the dispersion section; an output port; an optical path correction section that shifts the light that is dispersed by the dispersion section; an adjustment section that changes the amount of shift produced by the optical path correction section; and a casing that hermetically seals the input port, dispersion section, light-collecting element, output port, and optical path correction section. The casing has an optically transparent section in a location onto which the light that is collected by the light-collecting element is directed. The adjustment section is arranged outside the casing. The optical path correction section can be controlled from outside the casing by the adjustment section.
