Abstract:
An imaging processor for receiving a medium for processing, the processor comprising:(a) a print head for providing and for directing a writing laser beam;(b) means for creating a focusing laser beam for ultimately permitting adjustment of the writing laser beam;(c) an imaging receptacle for receiving the medium which is exposed to both the writing and focusing laser beams, said medium having leading and trailing edges so arranged as to expose a portion of the receptacle to the focusing laser beam, and the focusing laser beam is periodically directed from the medium to said exposed portion of the imaging receptacle and back to the medium; and,(d) a laser-absorbent coating coated onto said imaging receptacle for absorbing the focusing laser beam that is received by said exposed portion of the imaging receptacle for substantially eliminating transient oscillations in focusing of the writing laser beam.
