Abstract
780,976. Optical apparatus, hich speed kinematographic apparatus. REYROLLE & CO., Ltd., A. March 29, 1955 [March 29, 1954], No. 9110/54. Classes 97(1) and 98(1) Elements of an optical image in a primary image surface are transferred to and redistributed in a secondary image surface by means of a bundle of transparent rod or tube elements, primary ends of the elements lying in the primary image surface and secondary ends in the secondary image surface and the latter being laterally spread in comparison with the former, so that each secondary end lies on a separate strip of the secondary image surface. The secondary ends are thus able to record on the strips as recording tracks, the intensity of illumination at the primary ends or, if the secondary ends are illuminated, the intensity of their illumination is reproduced at the primary ends. The elements may be rods A of glass or quartz and their secondary ends are preferably tapered to concentrate the light passing therethough. As shown in Fig. 1 the secondary ends are arranged in a single straight line in the secondary image surface C and, they may be gripped between rubber-lined clamps. The primary ends are packed tightly together in a rubber-lined metal band in the plane B. Each element of the image formed at B by the lens D thus gives rise to a separate track on a photographic film carried on a drum E in as close proximity to the secondary ends as possible. A complete picture change can therefore take place when the thickness of the line is traversed by the film and thus, with a lens of sufficient relative aperture and sufficiently rapid film movement, extremely rapidly changing phenomena can be recorded. The same arrangement as in Fig. 2 is used for projecting the developed film, the drum E being made of translucent material and a strip lamp being arranged therein opposite the secondary ends; Instead of being arranged in a single straight line, the secondary ends may be arranged in zigzag formation in two spaced parallel straight lines. The untapered parts of the rods may be secured in this formation by using an internally screw-threaded tube with a thread pitch equal to the untapered rod diameter. The tube is cut away to leave only two thin prongs at the opposite ends of a diameter and the remaining part: of the thread grooves are then used with a thin rubber lining to locate the rods in position. The tapering is then arranged so that the tracks formed on the film just do not overlap. As a further alternative. the number of parallel straight lines may be equal to the number of rows of primary rod ends. In Fig. 3 (not shown), stiff short straight strongly tapered rods are used and their secondary ends are uniformly distributed in approximately the same formation as on the primary ends. The secondary ends are however arranged columnwise in echelon formation with respect to the direction of motion of the film so that each secondary end forms its own separate track on the film. These rods may be surface metallized, to retain the light, and embedded in a block of moulded material.
