    摘要： The illuminating system comprises a linear light source, and a light guide member with the light source placed beside a side face thereof, in which the top face and the bottom face of the light guide member are generally parallel to each other and in which slits made of a different material or air are arranged at specified intervals in the top face of the light guide member. Therefore, most of light propagating within the light guide member is totally reflected at the slits formed in the light guide member so as to be outputted from the light guide member, thereby illuminating a reflecting plate. Its reflected light is incident again on the light guide member and the resulting totally reflected light is transmitted to the observer's side at places other than the slits, while the observer's field of view is not obstructed at the slit portions.

    摘要： A low-cost wide-angle lens assembly being comprised of a decreased number of lenses yet capable of properly correcting optical aberrations. The second lens in each lens group from the minimum to the maximum horizontal viewing angle is commonly used, and the first lens in each lens group from a reference angle to the maximum horizontal viewing angle is commonly used, thus reducing the total number of required lenses. Aberrations are favorably corrected by satisfying predetermined conditions as to focal distances and back focuses of the lenses.

    摘要： An optical probe includes: an optical fiber; a substantially cylindrical ferrule integrally fixed to the optical fiber in the vicinity 2of the distal end of the fiber; a distal optical system for deflecting laser emitted from the optical fiber toward a subject to be measured; a holding portion for holding the distal optical system, the holding portion being supported by the ferrule rotatably about the optical axis of the optical fiber; a rotating oscillator slidably engaging with the outer circumferential surface of the ferrule; a driving unit for imparting oscillation in the direction of the optical axis to the rotating oscillator; and a coupling member for coupling the holding portion with the rotating oscillator elastically in the direction of the optical axis. The rotating oscillator rotates about the optical axis and reciprocates in the direction of the optical axis due to the oscillation applied from the driving unit.

    摘要： An optical tomographic image production apparatus includes an optical probe, in which a light-transmitting area that transmits measurement light and a light-blocking area that blocks the measurement light are formed. The light-blocking area is provided at a start position and an end position of the light-transmitting area. A tomographic image processing means detects an interference signal or tomographic information when the light-blocking area is irradiated with the measurement light. Further, the tomographic image processing means detects, based on the detected interference signal or tomographic information, interference signals or tomographic information obtained when the light-transmitting area is irradiated with the measurement light to produce a tomographic image in the light-transmitting area.
