  • Patent number: 4801188
    Abstract: A light guide optical device for guidance of light emitted from an original to an optoelectric transducer for converting the read out image of the original into electrical signals where the original is scanned line-by-line, is formed of a light conducting plate having a first linear side directed toward the original and a second side connected at the ends of the first side which is arcuately curved at least in regions. The plate includes a hole for accepting the transducer which receives light emitted from the surface of the plate at the hole.

  • Patent number: 4778994
    Abstract: An apparatus for converting image information generated by radiation incident on a storage layer into an electrical signal sequence by scanning the storage layer with a light beam permits a fast and precise conversion of the radiation image information into the electrical signal. This is a accomplished by connecting the scanned point of the storage layer to photodiodes functioning as light transducers via a light conductor in the form of a transparent, strip-shaped plate. The light conductor plate has a major surface adjacent to the storage area, and respective minor surfaces at opposite narrow ends thereof to which the photo diodes are connected. The apparatus can be used in x-ray television technology, such as medical x-ray diagnostics.
