Abstract

Device for detecting information which is contained in a phosphor layer, with a light source for emitting stimulation light incident upon the phosphor layer along a stimulation line is suitable for stimulating emission light in the phosphor layer, and a detector for detecting the emission light which is stimulated in the phosphor layer. To ensure the highest possible quality of the detected image, an elongated concave mirror is provided, for focusing the stimulation light emitted by the light source onto the phosphor layer. The light source is projected onto the phosphor layer at a scale of 1:M, where M takes a value between 0.5 and 2.
