ABSTRACT:
The invention relates to an apparatus for capturing information contained in a phosphor layer, comprising an irradiation device (4) for irradiating the phosphor layer (1) with stimulation light (3) which is adapted to stimulate emission light (7) in the phosphor layer (1), the irradiation device (4) including with the normal (L) on the phosphor (1) layer a first angle of inclination (αS), and comprising a detection device (10) for capturing emission light (7) stimulated in the phosphor layer (1), the detection device (10) including with the normal (L) on the phosphor layer (1) a second angle of inclination (αD).To reduce losses of intensity and definition it is provided according to the invention that the first angle of inclination (αS) of the irradiation device (4) and the second angle of inclination (αD) of the detection device (10) are selected such that components of the stimulation light (3) reflected by the phosphor layer (1) and then by the detection device (10) impinge on zones (15) of the phosphor layer (1) in which emission light (7) has already been stimulated.
