ABSTRACT:
An elliptical section mirror is placed with its concave side turned towards the surface of a stimulable phosphor panel to detect and deflect towards the second of its focal segments the light emitted by the phosphor after the scanning thereof with a stimulating ray passing through an opening of the mirror. The panel, the emitting surface and the emitting depth of the panel passes through the first focal segment of the mirror and the stimulating radiation impinges upon the panel, preferably in a perpendicular direction, along said first focal segment. A light guide having a straight-line inlet end placed in the second focal segment of the mirror is impinged upon by the light coming from the first focal segment and transfers it towards a photodetector through an outlet end.
