Patent ID: 7367682

Claim:
An image projection arrangement for projecting a two-dimensional, color image, comprising: a) a support; b) a laser assembly on the support, for emitting a plurality of laser beams of different wavelengths; c) a scanner on the support, for sweeping a pattern of scan lines in space at a working distance from the support, each scan line having a number of pixels; d) a controller operatively connected to the laser assembly and the scanner, for causing selected pixels to be illuminated, and rendered visible, by the laser beams to produce the image; and e) an optical assembly on the support between the laser assembly and the scanner, for focusing and substantially co-linearly arranging the laser beams to form a composite beam which is directed to the scanner, the optical assembly including a plurality of optical elements, one for directing each laser beam, and a corresponding plurality of holders, one for holding each optical element, for adjustably two-dimensional positioning of the respective optical element on the support for directing the respective laser beam into the co-linear arrangement of the composite beam.
