Abstract: An endoscope system includes: an illumination portion that includes a light source and that is configured to radiate an illumination light beam having a spatially nonuniform intensity distribution onto an imaging subject; a first imager and a second imager disposed at positions that are different from each other and configured to respectively acquire a first illumination image and a second illumination image of the imaging subject being illuminated with the illumination light beam; and at least one processor configured to: create a first deep-layer image and a first surface-layer image from the first illumination image and create a second deep-layer image and a second surface-layer image from the second illumination image; and create a combined deep-layer image by combining the first deep-layer image and the second deep-layer image on the basis of pixel values of the first and second surface-layer images.

Abstract: Provided is a display device that can be readily reduced in size and thickness, and is capable of reducing luminance unevenness within an image. The display device includes: a projection optical system that projects image light at infinity; and a first propagation optical system, a second propagation optical system, and a third propagation optical system, which sequentially enlarge, in one direction, the image light projected from the projection optical system, in which the image light output from the third propagation optical system allows an image to be observed.

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 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: A measurement probe is configured to be detachably connected to a biological optical measurement apparatus that performs an optical measurement on body tissue. The measurement probe includes an illumination fiber configured to irradiate the body tissue with illumination light, and a plurality of detection fibers configured to detect return light of at least one of the illumination light reflected from the body tissue and the illumination light scattered from the body tissue. On a plane which is away from distal ends of the illumination fiber and the plurality of detection fibers and through which the illumination light and the return light can pass, a detection area of the return light in each of the plurality of detection fibers is included in all of an illumination area of the illumination fiber or inside of the illumination area.
