Abstract
A scan assembly includes an emitter array containing a plurality of optical emitters. Each optical emitter generates a corresponding image beam and the scan assembly scans the image beams in a plurality of overlapping display zones. The overlap of adjacent image display zones forms blending zones and the scan assembly can modulate the intensities of the image beams as a function of the position of the image beams in the blending zones. This modulation for a given blending zone may be a linearly increasing intensity of a first image beam and a linearly decreasing intensity of a second image beam.
