    摘要: In an apparatus for the input of information, it is provided that a raster or an array of light-emitting screen elements is associated with a raster or an array of photodetectors, the light emitted by at least one of the screen elements being reflected to at least one of the photodetectors when an object approaches the apparatus; it is further provided that output signals of the photodetectors are used to obtain information on which of the photodetectors are receiving reflected light.

    摘要: A process for the fabrication of polymer layers structured in three dimensions, such as of lenses, which are applied to the end of optical fibers or of laser light sources. Dry resist that is polymerizable through exposure is used as a base substance. The dry resist is applied to a substrate and is exposed with a dose apportionment that is predefined as a function of space and time in a structure region. The structure region is precalculated with submicrometer precision using image-processing methods and exhibits the form of the desired lens. The lens-shaped structure region that is polymerized through exposure is removed from the unexposed dry resist. The process of the present invention makes it possible to place lenses on an optical fiber or a laser with submicrometer precision.

    摘要: In a device for optical coupling of a solid-state laser to an optical fiber, an anamorphic lens system is arranged between the output face of the solid-state laser and the input face of the optical fiber, the lens system converting differing apertures in the main sections of the solid-state laser into essentially identical apertures at the input face of the optical fiber. The lens system is composed of one anamorphic lens applied on the output face and a further lens applied on the input face.
