Abstract
To minimize the adverse effects of flare in a photostimulable phosphor read out apparatus, the input face of a light guide for guiding light emitted upon stimulation has an elliptical cross section. It is positioned so that one of the foci of the ellipse defining the elliptical cross section coincides with the scan line. The second focus is positioned above the scan line and in the vicinity of the second focus a light beam reflection preventing means is provided so that stimulation light reflected by the input face of the light guide is extinguished. In an alternative embodiment the light guide has a circular cross section and is positioned so that the axis of a cylinder comprising the input face does not coincide with the scan line.
