ABSTRACT:
Apparatus for scanning a photostimulable phosphor sheet includes a laser for forming a beam of stimulating radiation, and a photodetector for sensing radiation emitted from the sheet. An optical scanner scans the laser beam of stimulating radiation across the sheet to define a moving scanning spot and focuses light emitted from the phosphor sheet at the scanning spot onto the photodetector. The optical scanner includes a plurality of focusing mirror segments which are mounted to focus a spot on the phosphor sheet onto the photodetector and which are moveable for scanning the spot across the phosphor sheet with the beam of stimulating radiation being directed onto one of the mirror segments to focus on the spot.
