摘要： In a method and apparatus for point-by-point and line-by-line scanning of masters chucked on a scanner drum, for pixel-by-pixel illumination of the master, a light spot is generated with a light conductor, the light spot being imaged by a matching objective onto the master as an illumination spot. The scan light is focused with a scanner objective and is converted into an image signal in an opto-electronic scanner element. The illumination spot, scanner objective, and scanner element implement a feed motion in the direction of the rotational axis of the scanner drum for planar scanning of the master. Given employment of scanner drums having different diameters, the size of the illumination spot is corrected by a modification of the imaging scale of the light spot. The modification of the imaging scale occurs by displacing the light conductor with an actuating drive relative to the stationary matching objective. A corresponding focus correction occurs with a radial displacement of the scanner objective.

摘要： An opto-electronic arrangement for line-by-line scanning of color originals in reproduction technology by means of photodiodes as the opto-electronic transducers characterized by a light source with a condenser system whose light is projected at a fiber-optical shape converter, whose output cross section forms a linear optical pattern which is focussed further by a cylindrical lens into a band shape onto the original. In one embodiment, a filter wheel is provided between the light source and shape converter and in another embodiment the photodiodes are provided with dichroitic filters for selecting the color of the light received from the original into desired colored patterns. In another modification, the first cylindrical lens focusses the light onto a diffusing element and then a second cylindrical lens is present for focussing the light from the diffusing element directly onto the original. The light from the original is preferably received either by a macrolens and focussed onto the row of photodiodes or is received by a GRIN fiber optical arrangement for directing the light onto the photodiodes.
摘要翻译：一种用于通过光电二极管作为光电换能器在再现技术中逐行扫描彩色原稿的光电布置，其特征在于具有光源的光源，该光源具有光线投射在光纤形状转换器上的光源输出横截面形成线性光学图案，其进一步被柱面透镜聚焦成原始的带状。在一个实施例中，滤光轮设置在光源和形状转换器之间，在另一实施例中，光电二极管设置有二色性滤光器，用于将从原件接收的光的颜色选择为期望的着色图案。在另一变型中，第一柱面透镜将光聚焦到漫射元件上，然后存在第二柱面透镜，用于将来自扩散元件的光直接聚焦到原稿上。来自原稿的光优选地通过大光圈接收并聚焦到行的光电二极管上，或者由用于将光引导到光电二极管上的GRIN光纤装置接收。
