Apparatus to readout information from a phosphor layer

摘要

Device comprises an irradiation device (4) for illumination of a phosphor layer (1) with stimulating light (3) to cause fluorescing of the phosphor layer and a detection arrangement (10) for detection of the resultant fluorescent light. To minimize intensity and lost of contrast the inclination angles (alpha S, alpha D) of the irradiation device and detector are chosen so that reflected components of the stimulation light are only incident on areas (15) of the phosphor layer where emissive light has already been excited.
