More Information
Summary: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.
