    1. Optical imaging apparatus

      An optical imaging apparatus has an optical scanning probe configured to irradiate low-coherence light onto a subject and to perform photo-reception of light scattered at the subject, and an observation device adapted to construct a cross-section image of the subject based on information from the light received through the optical scanning probe. The optical scanning probe is detachably connected to the observation device.

    2. Light scanning devices of a water-tight structure to be inserted into a body cavity to obtain optical information on inside of a biological tissue

      A light scanning device has a tip structure which includes a light scanning part connected to a light source, and which is insertable into a body cavity and is formed so as to be water-tight. A controlling part controls the light scan through the tip structure, and the tip structure and the controlling part are also connected to each other in a water-tight manner by a slender tube through which a plurality of electrical cables pass. An electric connector is fixed with the proximal end portion of the tube in a water-tight manner, and is electrically connectable so as to ...

    3. Optical imaging apparatus which radiates a low coherence light beam onto a test object, receives optical information from light scattered by the object, and constructs therefrom a cross-sectional image of the object

      A low coherence beam emitted by a low coherence light source is split into two portions. One portion is transmitted from the outward end of a first single mode fiber via a detachable connector to a beam scanning probe, and then to a biological tissue; and the other is transmitted from an optical coupler placed midway along the light path via a second single mode fiber to a light path modifier. The light path modifier includes a galvanometer mirror to modify the light path length in accordance with a scan range, and a uniaxial stage to adjust the light path ...
