Abstract
A compact light projection system. The light projection system includes a light source, an anamorphic reflector assembly, and a correction element that is configured to mitigate aberration. The light source is configured to emit image light. The anamorphic reflector assembly includes a first surface and a second surface. The first surface is configured to reflect the image light toward the second surface which reflects the reflected image light to output it from the anamorphic reflector assembly. And the first surface and the second surface are both curved and non-rotationally symmetric such that the light output from the anamorphic reflector assembly is collimated image light. The collimated image light is optically corrected based in part on mitigation of aberration by the correction element.
