Title:
HIGH-RESOLUTION IMAGE PROJECTION
Document Type and Number:
WIPO Patent Application WO2003098916
Kind Code:
A3
Abstract:
A lightweight (Fig. 1), compact image projection module (10, 20), especially for mounting in a housing (10) having a light-transmissive window (60), is operative for causing selected pixels in a raster pattern to be illuminated to produce an image (30, 40) of high resolution of VGA quality in monochrome, color or gray scale. Pixel size is controlled as a function of distance of the image (30, 40) from the module (10, 20) to control image resolution and allow the image (30, 40) to remain sharp and clear over an extended range of distances from the module (10, 20).
