Abstract
System and method for scanning light across a light-receiving surface. A system for scanning light across a light-receiving surface to project a scanned line on the light-receiving surface has a light beam generator for generating a plurality of light beams. A scanning mechanism simultaneously scans each light beam of the plurality of light beams across the light-receiving surface to project a different portion of the scanned line on the light-receiving surface. The scanning system can be utilized in a compact laser printer capable of printing at a high rate, and in other scanning applications.
Claims30
A system for scanning light across a light-receiving surface to project a scanned line on the light-receiving surface, comprising:
- a light beam generator for generating a plurality of light beams;
- and
- a Micro-Electro-Mechanical System scanning mechanism for simultaneously scanning each light beam of the plurality of light beams across the light-receiving surface to project a different portion of the scanned line on the light-receiving surface.
A method for scanning light across a light-receiving surface to project a scanned line on the light-receiving surface, comprising:
- generating a plurality of light beams;
- and
- simultaneously scanning each light beam of the plurality of light beams across the light-receiving surface with a Micro-Electro-Mechanical System scanning mechanism to project a different portion of the scanned line on the light-receiving surface.
A laser printer, comprising:
- a drum;
- and
- a system for scanning light across a surface of the drum to project a scanned line on the surface of the drum, the system comprising:
- a light beam generator for generating a plurality of light beams;
- and
- a Micro-Electro-Mechanical System scanning mechanism for simultaneously scanning each light beam of the plurality of light beams across a surface of the drum to project a different portion of the scanned line on the surface of the drum.
