Abstract
Techniques are described for reducing safety-relevant emission of a laser projection system. A multi-facet optical element is positioned in the path of a raster-scanning laser beam. Each facet of the optical element is angled to redirect a projected pixel to a different pixel position. Collectively, the facets are configured to convert the projected raster scan into a non-raster scan in which physically proximate pixels are illuminated temporally non-proximate times.
