Abstract
A display system for presenting visual information to a user includes a fast scan mirror, a slow scan mirror, and anamorphic relay optics positioned optically between the fast scan mirror and slow scan mirror. The fast scan mirror has a fast scan arc in a scan direction of a display light provided by a light source. The slow scan mirror has a slow scan arc in a cross-scan direction of the display light that is perpendicular to the scan direction. The anamorphic relay optics are configured to magnify the display light in the cross-scan direction.
