Abstract

Device for the optical scanning of a recording medium, especially a phosphor storage plate (12), with a scanning head (10) which can move in relation to the recording medium and contains an imaging system in the form of an extended rotation-ellipsoidal mirror (14). The ellipsoidal mirror (14) has an inlet aperture (16) and an outlet aperture (18) at opposite ends. A scanning laser beam (30) impinges obliquely on the storage plate (12) moving past the inlet aperture (16). A reverse-tapering chamber (20) and a photodetector (24) are connected to the outlet aperture (18).
