Abstract: A light transmitting assembly utilizing fiber optic elements to pass light from a source to a sensing station. The assembly includes a mounting block or body for the fiber optic elements, having a single input channel adjacent the light source and plural output channels located adjacent the sensing station. The fiber optic elements are arranged in layers in the input channel, and each layer is randomly arranged in a separate output channel. Shadows cast on the input end of the fiber optic elements are diffused or averaged out over the layers, and a substantially equal amount of light emanates from each output channel.

Abstract: A target assembly for a storage/display deformographic tube comprising a Fabry-Perot type interference filter deposited on a dielectric target material. The filter comprises a deformographic film sandwiched between two mirrors, the inner dielectric mirror comprised of a quarter wavelength stack of alternating layers of materials with greatly differing indexes of refraction and the outer conducting mirror comprising a thin layer of appropriate metal such as silver. The deformographic film should be deposited in a layer which is an integral number of one-half wavelengths.

Abstract: The target of the information projection tube is made from a dielectric surface which provides a deforming mirror (36) and a transparent series of Fabry-Perot filters (22). A writing electron-gun (16) forms a charge on the target which deforms the mirror surface. A light source (60) is directed through an optical system into the target and, due to the interference action of the filters, creates a coloured pattern on an optical screen (74). An erase-gun (28) is also provided. The target can be made of alternate layers of zinc sulphide and cryolite with a mirror of deposited silver. This provides colour projection of the electron-gun information instead of the black and white display in previous tubes using Schlieren optics.

Abstract: 1289388 Light distributing assemblies INTERNATIONAL BUSINESS MACHINES CORP 16 Feb 1970 [28 March 1969] 7293/70 Heading G2J A light distributing assembly 10 comprises a light source 36 arranged in operation to illuminate an input window, such illumination being non- uniform having a zone of different intensity from the remainder of the window illumination, a plurality of fibre optic bundles, each bundle having an input and located in the input window and its output end in an individual output window, the input ends of the bundle being arranged so as to have equal proportions of their areas lying in said zone, and the fibres of each bundle being randomly distributed in the appropriate output window whereby illumination over each window is substantially uniform. The fibres in the input end of each bundle are arranged in horizontal layers when the light source is a lamp providing illumination with vertically extending dark zones, and the bundles are arranged in a mounting block 40 having an output face 42. The assembly 10 is used with a device 12 programmed to control a motor 20 of, for example, a key punch. When one of the holes 26 in a punched card 28 wound round a drum 14 corresponds with one of a plurality of holes 24 in a drum 14 and is aligned with a sensing device 38, the light from one of the output windows passes through the holes onto a corresponding photoresponsive element such as a photo-transistor in the sensing device 35. The arrangement of the fibres in the output window may be adapted to diffuse light from any non-uniform source, for example, by arranging the bundles of fibres radially to diffuse a circular dark zone of illumination. To manufacture the light distributing assembly, shims 61 Fig. 6 (not shown) used initially to separate the layers of fibres in the input window, are removed before the fibres are potted into the mounting block 40.
