Abstract

A device for acquiring information that is contained in a phosphor layer which includes a light source (2) for irradiating and exciting the phosphor layer (1) to produce emission light (4) containing the information, a detector (6) for acquiring the emission light (4) produced in the phosphor layer (1) and a filter device (8), which is arranged between the phosphor layer (1) and the detector (6) and/or between the phosphor layer (1) and the light source (2). To increase the reliability in the acquisition of the emission light (4), the filter device (8) includes at least two filter elements structured as absorption filters and joined to each other.
