Patent ID: 7357512

Claim:
An image projection system for projecting a two-dimensional, color image, comprising: a projection screen; a laser assembly including red, blue and violet solid-state, semiconductor lasers for emitting a composite beam comprised of a plurality of red, blue and violet laser beams, respectively, of different wavelengths toward the projection screen; a collimating lens for collimating the laser beams; a lenticular lens array having a plurality of lenses for focusing the collimated laser beams at a focusing plane; a mask having apertures lying in the focusing plane; a scanner for sweeping the composite beam in a pattern of scan lines across the projection screen, each scan line having a number of pixels; a controller operatively connected to the laser assembly and the scanner, for causing selected pixels to be illuminated, and rendered visible, by the composite beam to produce the image; and a phosphor in the apertures of the mask, for converting one of the laser beams having a wavelength to a different wavelength to create the image in red, blue and green colors.
