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 ().

Device for acquiring information contained in a phosphor layer

A device for acquiring information that is contained in a phosphor layer which includes a light source () for irradiating and exciting the phosphor layer () to produce emission light () containing the information, a detector () for acquiring the emission light () produced in the phosphor layer () and a filter device (), which is arranged between the phosphor layer () and the detector () and/or between the phosphor layer () and the light source (). To increase the reliability in the acquisition of the emission light (), the filter device () includes at least two filter elements structured as absorption filters and joined to each other.
