    摘要： 1. In combination an opaque main supporting housing and a combined light-collecting and detecting system disposed within and surrounded by said main housing at a location intermediate its spaced opposite ends, said combined system comprising a single set of similar relatively small peripherally arranged light apertures in side wall portions of said main housing and appreciably spaced from each other in such a predetermined manner as to have each light aperture face outwardly in a different azimuthal direction, and jointly simultaneously admitting into said housing light from all parts of two different predetermined endless annular object fields outwardly of said housing and in concentric relation to a longitudinal axis extending centrally through said housing, a pair of relatively small photosensitive detecting elements disposed respectively at spaced axial locations in said main housing and each being arranged to detect any appreciable change in light intensity occurring at any location in the respective endless annular object field associated therewith, a pair of optical systems associated with each light aperture, and each optically aligned with a respective one of said spaced detecting elements, and each of said optical systems comprising a plurality of specularly reflecting surfaces including a plane surface and a curved surface in optical alignment with each other, said plane surface being positioned within said housing in a plane substantially parallel to the light aperture associated therewith and at a location substantially midway between the aperture associated therewith and said central longitudinal axis, said curved surface being a concavely curved surface having its center of curvature disposed substantially upon said longitudinal axis, said plane surface being so disposed in said housing and relative to the light aperture associated therewith as to intercept substantially all of the light rays from the object field aligned therewith which enter said housing, and to reflect same toward said curved surface, and said curved surface being so disposed in said system as to receive said reflected light rays and direct same inwardly as a convergent bundle of light rays generally toward the detecting element associated therewith, and a pair of positive lens elements centrally disposed within said housing, and each in optical contact with one of said detecting elements so as to collect the light rays travelling beyond the curved surface aligned therewith and to direct same onto said detecting element associated therewith.

    摘要： An optical fiber array, which converts an arcuate image to a plane image with minimum of distortion, is provided by forming multifilament fibers into multiple fiber units which are bent, nested together and then trimmed to form an arcuate image plane on one side subtending the desired input arc and forming a flat, planar image plane on the other side of the array.
