Abstract

The display may comprise a light source to generate a light beam, a scanning platform to generate a raster scan from the light beam projected as a projected image, one or more post-scan optics to at least partially adjust the projected image, and one or more collimating optics to focus the light beam from the light source, the one or more collimating optics having a selected focal length to at least partially provide infinite, or nearly infinite focus, of the projected image at or beyond a selected distance.
