摘要： The stereoscopic microscope includes a common close-up optical system that faces an object, a pair of zoom optical systems that form a pair of primary image, a pair of field stops, a pair of relay optical systems that relay the primary images to form a pair of secondary images, an inter-axis distance reducing element, an image taking device and an illuminating optical system. The object light rays incident on the close-up optical system form the primary images having predetermined parallax at the field stops through the zoom optical systems. The inter-axis distance reducing element reduces the inter-axis distance of the right and left light rays. The primary images are re-imaged by the relay optical systems as the secondary images on the adjacent regions on the single image taking surface of the image taking device, respectively.

摘要： An endoscope system is provided with a light guide including a plurality of optical paths, and a low-coherent light source that emits a low-coherent light beams. The low-coherent light source is provided at a proximal end side of the light guide. The light beams emitted by the low-coherent light source are incident on the plurality of optical paths, respectively. The endoscope system is further provided with an interferometer unit. The interferometer unit includes a beam splitting element that splits each of the low-coherent beams emitted from the distal end of the light guide and emits split one of each of the beams to an object, a reference optical system that guides the other split beam of each of the beams, a reflector unit that reflects the beams guided by the reference optical system toward the beam splitting element, and a light detecting device that detects an interfered beam generated by interference, at the beam splitting element, between the beam reflected by the object and the beam reflected by the reflector unit. The endoscope system is further provided with a driving unit that moves the interferometer unit toward/away from the object, and a signal processing system that generates a tomogram based on signals detected by the light detecting device.

摘要： PROBLEM TO BE SOLVED: To provide diagnostic light irradiation apparatuses for obtaining excellent light coupling efficiency between a light source device and a fiber probe regardless of the fiber probe to be connected.
SOLUTION: The diagnostic light irradiation apparatuses (100, 200, 300) irradiate a prescribed part in a body with a diagnostic light for optically diagnosing the prescribed part of the body. These apparatus include: a light supply means (110) for supplying the diagnostic light; and a light transmitting means (104) which is attached/detached to/from the light supply means, and at least a part of which is inserted to the body in order to allow the prescribed part of the body to be irradiated with the diagnostic light supplied from the light supply means. The light transmitting means is formed to be able to be inserted into the body through a channel in the treatment implement of an endoscope, so that it is easily inserted into the body by using the existing endoscope. The apparatuses also include an adjusting means (132) for adjusting the optical coupling state of the light supply means with the light transmitting means arranged in the light supply means.

摘要： PROBLEM TO BE SOLVED: To provide a flexible endoscope which can continuously detect and display the bent state and its change of an inserting section flexible tube which is inserted in the body without exposure to radiation.
SOLUTION: This flexible endoscope has the flexible inserting section flexible tube 1. In such a flexible endoscope device, a plurality of flexible optical fibers 21 for bend detection are attached to a flexible band-shape member 20 under a state being arranged in parallel, and insert-arranged extending to the approximately total length in the inserting section flexible tube 1. In this case, the optical fibers 21 have a bend detecting section 22 of which the light transmission amount changes in response to the size of a bent angle. Then, the bent states of the band-shape member 20 at areas where respective bend detecting sections 22 are located are detected from the light transmission amounts of respective optical fibers 21 for the bend detection. The bent states are displayed on a monitor screen 41 as the bent state of the inserting section flexible tube 1.
