1. An image projection module for projecting a two-dimensional image, comprising: a) a support, b) a laser on the support, for emitting a laser beam; c) a scanner on the support, for sweeping a pattern of scan lines in space at a variable distance from the module, each scan line having a number of pixels; d) a controller operatively connected to the laser and the scanner, for causing selected pixels to be illuminated, and rendered visible, by the laser beam to produce the image; and e) optics on the support, for controlling pixel size as a function of the variable distance of the image from the module to control resolution of the image over an extended range of distances from the module.
