Device for reading out X-ray information stored in a storage phosphor layer, comprising - a light source for generating a stimulating light beam, which is able to stimulate the storage phosphor layer to have it emitting emission light, - a deflection element for deflecting the stimulating light beam in such a way that the deflected stimulating light beam is moved across the storage phosphor layer, - a drive equipment for driving the deflection element, said deflection element comprising a reflecting area, which is made to move oscillatingly by the drive equipment, and - a detector for detecting emission light which is emitted by the storage phosphor layer while the deflected stimulating light beam moves in a first direction of movement across the storage phosphor layer and the deflection element moves in a first direction, characterized in that the detector is designed in such a way or the device is controlled in such a way that the detector does not capture emission light when the deflected stimulating light beam moves in a second direction of movement which is opposite to the first direction of movement and the deflection element moves in a second direction which is opposite to the first direction, at least one sensor element (10, 11) is provided for detecting the position of the deflected stimulating light beam and a control unit is provided for controlling the drive equipment in such a way that - drive energy is pulse-wise released to the deflection element as function of the detected position of the deflected stimulating light beam, said release of drive energy to the deflection element being triggered when the deflected stimulating light beam moves in the second direction of movement, and - the release of drive energy to the deflection element only then takes place when the deflected stimulating light beam moves in the second direction of movement and the deflection element moves in the second direction. - a light source for generating a stimulating light beam, which is able to stimulate the storage phosphor layer to have it emitting emission light, - a deflection element for deflecting the stimulating light beam in such a way that the deflected stimulating light beam is moved across the storage phosphor layer, - a drive equipment for driving the deflection element, said deflection element comprising a reflecting area, which is made to move oscillatingly by the drive equipment, and - a detector for detecting emission light which is emitted by the storage phosphor layer while the deflected stimulating light beam moves in a first direction of movement across the storage phosphor layer and the deflection element moves in a first direction, characterized in that the detector is designed in such a way or the device is controlled in such a way that the detector does not capture emission light when the deflected stimulating light beam moves in a second direction of movement which is opposite to the first direction of movement and the deflection element moves in a second direction which is opposite to the first direction, at least one sensor element (10, 11) is provided for detecting the position of the deflected stimulating light beam and a control unit is provided for controlling the drive equipment in such a way that - drive energy is pulse-wise released to the deflection element as function of the detected position of the deflected stimulating light beam, said release of drive energy to the deflection element being triggered when the deflected stimulating light beam moves in the second direction of movement, and - the release of drive energy to the deflection element only then takes place when the deflected stimulating light beam moves in the second direction of movement and the deflection element moves in the second direction.
