Phosphor plate reading apparatus, comprising: - stimulating means for supplying a stimulating energy flux to an entire transverse band of a phosphor plate to be read; - at least one readout unit having an input window for collecting phosphorescent radiation generated by portions of the phosphorescent plate in response to the stimulating energy flux, and further having at least one image sensor and an optical system arranged such that it transmits the phosphorescent radiation from the input window to the image sensor; and - a drive mechanism adapted to guide and displace the plate to be read so that the plate is moved past the stimulating means and the input window of the readout unit , the image sensor capturing an image of the entire transverse band of the plate to be read, formed by the phosphorescence radiation, while the plate is moved translationally, the image sensor is of the time-shifting and integrating matrix image sensor type, and the reader is adapted so that the time-shifting and integrating matrix image sensor has a line transfer rate which is parallel and correlated with a driving speed of the disk by the driving mechanism, the stimulating means are arranged downstream of the input window of the readout unit with respect to a translational direction of the plate to be read, for supplying the stimulating energy flux to the plate in the form of a stimulating light beam incident to the plate from a same side as the readout unit and which simultaneously scatters over the entire transverse band of the plate to be read as far as in front of the input window of the readout unit with respect to the direction of displacement of the plate, the optical system comprising, starting from the input window for the phosphorescent radiation, a bundle of optical fibers whose optical axis is perpendicular to the plate to be read. - stimulating means for supplying a stimulating energy flux to an entire transverse band of a phosphor plate to be read; - at least one readout unit having an input window for collecting phosphorescent radiation generated by portions of the phosphorescent plate in response to the stimulating energy flux, and further having at least one image sensor and an optical system arranged such that it transmits the phosphorescent radiation from the input window to the image sensor; and - a drive mechanism adapted to guide and displace the plate to be read so that the plate is moved past the stimulating means and the input window of the readout unit , the image sensor capturing an image of the entire transverse band of the plate to be read, formed by the phosphorescence radiation, while the plate is moved translationally, the image sensor is of the time-shifting and integrating matrix image sensor type, and the reader is adapted so that the time-shifting and integrating matrix image sensor has a line transfer rate which is parallel and correlated with a driving speed of the disk by the driving mechanism, the stimulating means are arranged downstream of the input window of the readout unit with respect to a translational direction of the plate to be read, for supplying the stimulating energy flux to the plate in the form of a stimulating light beam incident to the plate from a same side as the readout unit and which simultaneously scatters over the entire transverse band of the plate to be read as far as in front of the input window of the readout unit with respect to the direction of displacement of the plate, the optical system comprising, starting from the input window for the phosphorescent radiation, a bundle of optical fibers whose optical axis is perpendicular to the plate to be read. <EOS>
