Abstract
An arrangement for reading photo-stimulable storage luminescent substances comprises an excitation glass fiber into which light which excites the storage luminescent substance can be fed by means of a light source. Light emitted by the excited storage luminescent substance can be fed into a receiving glass fiber, an end of the excitation glass fiber which is positioned close to the storage luminescent substance being arranged next to an end of the receiving glass fiber which can be positioned close to the storage luminescent substance. The excitation glass fiber (12) has a first numerical aperture and the receiving glass fiber has a second numerical aperture which is large compared with the first numerical aperture, as a result of which the light fed out from the excitation glass fiber is directed straight onto the storage luminescent substance without an optical arrangement and the stimulated light can be captured by the receiving glass fiber without an optical arrangement. A glass fiber drum scanner uses the arrangement for reading photo-stimulable storage luminescent substances to achieve a two-dimensional readout of the storage luminescent substance by means of an advancing dev…
