Abstract:
1. An image projection arrangement for projecting a two-dimensional image on a projection surface, comprising: a) a laser assembly for generating a laser beam; b) a scanner for sweeping the laser beam as a pattern of scan lines at a distance from the laser assembly on the projection surface, the scanner including a scan mirror movable at a speed that varies along each scan line, each scan line having a number of pixels, the pixels having respective time durations proportional to the variable speed of the scan mirror; c) a profile memory for storing the time durations of the pixels; and d) a controller operatively connected to the laser assembly, the profile memory and the scanner, for causing selected pixels along the scan lines to be illuminated for the time durations stored in the profile memory, and rendered visible, by the laser beam to produce the image.
