Abstract
A scanning optical system comprises a gas laser beam source for emitting a laser beam which causes a stimulable phosphor sheet carrying a radiation image stored therein to release the stored energy of the radiation as light emission, optical members for scanning the stimulable phosphor sheet with the laser beam, and a beam expander positioned between the optical members and the gas laser beam source. The angle of incidence of the laser beam is adjusted by the optical members so that the direction of the incident laser beam is always different from the direction normal to the surface of the stimulable phosphor sheet. Thus the laser beam reflected by the stimulable phosphor sheet is prevented from being fed back along the same optical path as that of the incident laser beam.
