ABSTRACT:
A device for reading flexible storage foils. The devices includes a foil support, a reading light source which provides a reading light beam which has a wave length suitable to excite metastable storage centers of the storage foil. Drive mechanisms are employed to provide relative movement between the reading light beam and the storage foil. A light detector is responsive to fluorescence light of the storage foil generated by the reading light beam.
