Patent Searching and Data


Document Type and Number:
Japanese Patent JPH0577228
Kind Code:
B2
Abstract:
An apparatus for scanning a transparency image original wherein scattered light emerging from the original is guided through lens or diffraction gratings onto a diffusion screen attached to a light mixer. In the light mixer, the light is mixed by multiple reflection and, at a light exit of the mixer, is guided to a cross-sectional transducer formed of a plurality of optical fibers. These fibers conduct the light onto a photoelectric transducer. The apparatus works with high efficiency and reduces an image falsifying influence of the Callier effect to such a degree that it no longer has a disturbing appearance in reproduction.
