Abstract
A device for acquiring information contained in a phosphor layer comprises a light source () for irradiating the phosphor layer () with excitation light () that is suitable for exciting emission light () in the phosphor layer (), a detector () for detecting the emission light () that has been excited in the phosphor layer (), and a filter device (), arranged between the phosphor layer () and the detector (), that is substantially transparent in a first wavelength range (W) of the emission light () and substantially non-transparent in a second wavelength range (W) of the excitation light (). To increase the reliability during the acquisition of the emission light, the filter device () is made substantially non-transparent in at least a third wavelength range (W) having longer wavelengths than the second wavelength range (W) of the excitation light ().
