Patent ID: 7466331

Claim:
A multiple beam scanning system for scanning a plurality of light beams onto a predetermined surface in a predetermined scan direction, the scanning system comprising: a light source for generating the plurality of light beams along a first light path; a first input and output telecentric optical subsystem including at least one optical element aligned to redirect the plurality of light beams along a second light path; a deflector including a reflection surface that periodically intersects an end of the second light path, and means for moving the reflective surface such that the plurality of light beams are periodically scanned along a first scan path; and a second input and output telecentric optical subsystem including a plurality of optical elements that are sequentially optically aligned to receive the light beams scanned along the first scan path, and to redirect the scanned plurality of light beams along a second scan path onto the predetermined surface, wherein the plurality of optical elements of said second input and output telecentric optical subsystem comprise a positive cross-scan cylindrical first optical element, a negative cross-scan cylindrical second optical element, and a positive cross-scan cylindrical third optical element.
