Abstract:
1. An image projection arrangement for projecting a two-dimensional image, comprising: a support extending along mutually orthogonal dimensions; a laser assembly including a plurality of lasers on the support, for respectively generating a plurality of laser beams of different wavelengths; an optical assembly on the support, for focusing and nearly collinearly arranging the laser beams to form a composite laser beam; a scanner on the support, for projecting the composite laser beam as a pattern of scan lines on a generally planar projection surface at a distance from the support, each scan line having a number of pixels, the pattern extending along mutually orthogonal directions respectively generally parallel to the mutually orthogonal dimensions of the support; and a controller operatively connected to the laser assembly and the scanner, for causing selected pixels to be illuminated, and rendered visible, by the composite laser beam to produce the image.
