Abstract:
1. An apparatus for capturing information contained in a phosphor layer, comprising: an irradiation device for irradiating the phosphor layer with stimulation light which is adapted to stimulate emission light in the phosphor layer, the irradiation device being inclined at a first angle of inclination (α a detection device for capturing emission light stimulated in the phosphor layer, the detection device being inclined at a second angle of inclination (α wherein the irradiation device is arranged ahead of the detection device with respect to a transport direction (T) in which said apparatus is moved relative to the phosphor layer, wherein the first angle of inclination (α wherein the first angle of inclination (α wherein the first angle of inclination (αs) of the irradiation device is not more than the 10° greater than a sum (α wherein the stimulation light of the irradiation device impinges on the phosphor layer in a stimulation light line and the detection device is arranged to capture the emission light issuing from a second zone of the phosphor layer, the second zone being offset with respect to the stimulation light line by a distance in the transport direction T in which the apparatus is moved relative to the phosphor layer.
