Abstract: The invention relates to an optical anamorphoser and to its method of manufacture in which a bundle of fibers (3) is deformed by twisting, is imprisoned in a body (5), and is sliced along two planes (2 and 3) perpendicular to its axis (4).

Abstract: The device comprises an extension of a radiation conductor of constant cross-section, having a radiations-confining interface of truncated shape, of which the directrices and generatrices can be any type.According to the invention, said device comprises at least a second radiations-confining interface of conical shape situated inside the first interface, the distance between these two radiations-confining interfaces being substantially constant, and said two interfaces facing in such a way that the radiations are confined between them and propagate towards or from the widened end of the interface opposite the conductor.

Abstract: The electro-optical image display device according to the invention comprises one or more identical integrated circuits connected to a control printed circuit, each integrated circuit comprising a semiconductor and transducer chip protected by a transparent window; every integrated circuit cooperates with an image expander constituted by a bundle of optical fibers which, on the object side, are virtually contiguous and applied by their ends against the window of the integrated circuit whereas, on the image side, said fibers are kept regularly spaced apart; the image expanders cooperate with a recomposer in plastic material which magnifies at least partly the image-pixels and adjust them on the borderline of the expanders.

Abstract: A support element is disclosed for conveying encoded information, such as arabic numerals, formed of detectable material in presentable form for automatic decoding. The support surface is characterized by one or more information displays each of which is patterned from a pair of adjacent quadrilaterals preferably joined along a common segment to form a grid, each display being characterized by the detectable material overlying selected grid segments. A plurality of displays may be aligned on the support one behind the other such that corresponding grid segments from a pair of adjacent displays are inscribed within one of three parallel grid sampling channels delimiting all the segments of at least one grid. Automatic detection of the encoded numerals is accomplished by traversing the displays with a suitable sensor in one direction within the boundaries of each of the sampling channels. Where the displays are to be hand written the detectable material may be provided by preprinted or impressed supports.
