  • Patent number: 7148933
    Abstract: A projector employing a linear array of light-emitting sources forms a super pixel in the form of a plurality of beams that are focused onto scanning optics that cause the beams to move across a viewing surface on a first axis for defining image lines along the first axis and on a second axis such that super pixel overwrites every addressable spot on the viewing surface thereby producing interleaved and staggered scan patterns that hide the effect of burned out, misdirected, or marginally operating light-emitting sources that would otherwise result in a degraded projected image. An alignment system that includes alignment electronics that is responsive to a charge-coupled device facilitate adjusting the scanning optics to allow precise alignment of individual ones of the light-emitting sources and to detect burnt out individual ones of the light-emitting sources.
