Abstract
A read-out system for a luminescent storage screen of the type used in an x-ray diagnostics installation has a scan beam generator which generates a scan beam of a first wavelength, a beam deflector for deflecting the scan beam to planarly scan a luminescent storage screen pixel-by-pixel to retrieve the stored image, the scan beam causing the storage screen to luminesce and generate light of a second wavelength which is detected by a detector system. The detector system includes a light conductor which conducts the light onto a light detector. The detector system includes a filter for light of the first wavelength, which is arranged in the immediate proximity of the point of incidence of the scan beam on the luminescent storage screen. The filter is in the form of a slot-shaped opening for the scan beam.
