Claim One:
1. An image projection arrangement for projecting a two-dimensional, color image, comprising: a support; a laser assembly on the support, including a laser package having a common exit port, and a plurality of lasers mounted in the package and operative for emitting a plurality of laser beams of different wavelengths through the common exit port; an optical assembly on the support, for focusing the laser beams exiting the common exit port, including a common focusing lens through which the laser beams pass along respective paths that are in angular misalignment, and an optical corrector element in at least one of the paths for correcting the misalignment to produce aligned beams; a scanner on the support, for sweeping the aligned beams in a pattern of scan lines in space at a working distance from the support, each scan line having a number of pixels; and a controller operatively connected to the laser assembly and the scanner, for causing selected pixels to be illuminated, and rendered visible, by the aligned beams to produce the image.
