Abstract

The invention relates to a method of reading out information items stored in a phosphor layer, in which the phosphor layer is excited to emit emission light and the emission light is sensed by a detector and the detector is moved relative to the phosphor layer. During this process, the detector consecutively senses the emission light emitted in each case by individual regions of the phosphor layer. To reduce the dark noise and the movement blur, provision is made that the detector senses the emission light emitted by a region during an integration time that is less than a forward-travel time for the movement of the detector by the width of the region in the forward-travel direction (V).
