Abstract

A photodetector CCD pick-up device reads a storage phosphor record carrier via a light source on one side of the carrier with the photodetector device on the other side of the carrier. A drive displaces the carrier relative to the light source and to the CCD device. The light source illuminates the phosphor sub-surface of the record carrier to produce fluorescent light and which sub-surface comprises a plurality of pixels. The CCD pick-up device is arranged so that the charges in its cells produced by the fluorescent light displace in the same direction and at the same speed as the carrier.
