Abstract: In a three-dimensional imaging device, plural optical fibers which are provided with a lens characteristic by a refractive index distribution which is not uniform in a radial direction, such as a square-law characteristic, and which has the same length are configured so that the length &thgr; is an odd-number multiple of a half period of an optical path, and both ends of the optical fibers are arranged in the same two-dimensional manner. The configuration is used in a plural number so that a three-dimensional object is three-dimensionally imaged and the image is transmitted.

Abstract: An autostereoscopic image apparatus for picking-up an autostereoscopic image and optically transmitting and displaying the autostereoscopic image. The autostereoscopic image apparatus is constructed by an assembly of a plurality of optical fibers each having an equal length and a lens function. The length of each of a plurality of optical fibers is equal to a length that is integer times as long as one period of an optical path in the optical fiber. The first edge surface of each of a plurality of optical fibers is located on the same plane and forms the first edge surface of the optical fiber assembly. The second edge surface of each of a plurality of optical fibers is located on the same plane and forms the second edge surface of the optical fiber assembly. An arrangement at the first edge surface of the optical fiber assembly at the edge surfaces of a plurality of optical fibers and an arrangement at the second edge surface are equal.

Abstract: A board is provided with a plurality of spaced conductors, covered by a waterproof film on one surface thereof, with a window through the film exposing selected portions of the conductors. A connector housing supports a plurality of electrical contacts that are brought into electrical management with the conductors through the window. A compressible ring surrounds the housing contacts and the window and is sandwiched between the board and the housing. A spring-biased holding member, latched to the housing, urges the board resiliently toward the housing, causing the electrical engagement between the board conductors and the housing contacts and also compressing the ring around the window to provide a waterproof seal around the electrical junctures.
