Method and apparatus for scanning regions |
December 18, 2007 |
| A beam scanner is operable to scan light in two or more axes, typically in a raster pattern that includes a fast scan axis and a slow scan axis. Plural beams of light are scanned, each beam of light producing a scanned region that at least partially overlaps at least one adjoining scanne |

Scanned beam display having compensation for pattern dependant heating of a light source |
January 2, 2007 |
| A scanned beam display includes compensation for pattern-dependant heating of a light source. According to some embodiments, received image data is transformed to corrected data that compensates for pattern-dependent heating of one or more light sources. |
