Abstract
A head mounted display (HMD) system includes a light source, a scanning mirror assembly, and an output screen. The light source includes source elements that emit image light. The scanning mirror assembly scans the image light at least along one dimension to form tiled portions of scanned image light of an output image. The scanning mirror assembly directs at least one of the tiled portions of the output image to a first position, and redirects at least one of the tiled portions of the output image to a second position adjacent to the first position. The scanning mirror assembly includes scanning mirrors operating within a first range of scanning frequencies along a slow axis and a second range of scanning frequencies along a fast axis. The output screen outputs a tiled image light to an eyebox region using the scanned image light.
