ANORDNUNG ZUM AUSLESEN PHOTOSTIMULIERBARER SPEICHERLEUCHTSTOFFE

A receiving glass fibre (14) is provided into which the light coming from the excited accumulative luminescent material (34) is fed. One end (12a) of the excitation glass fibre (12), which is positionable near to the accumulative luminescent material, is arranged next to an end (14a) of the receiving glass fibre (14) near to the accumulative luminescent material (34). The excitation glass fibre (12) has a first numerical aperture. The receiving glass fibre (14) has a large second numerical aperture in relation to the first numerical aperture. The light coming from the excitation glass fibre is directed without optical arrangement directly to the accumulative luminescent material (34). USE/ADVANTAGE - For reading photo-stimulatable accumulative luminescent material, particularly in dental practice. A glass fibre drum scanner applying the principles of the invention is less costly to produce.
