Claim One:
1. A scanning laser projector, comprising: at least one source of laser light, the at least one source of laser light configured to generate a laser beam; at least one scanning mirror configured to reflect the laser beam in a pattern of scan lines; and an output optic configured to receive the reflected laser beam and output the reflected laser beam to project an image on a display surface, wherein the output optic includes: a prism having a first surface, a second surface, and a third surface, wherein the first surface, the second surface, and the third surface have freeform rotationally asymmetric shapes; a mirror, the mirror including a mirror surface having a freeform rotationally asymmetric shape; and wherein the freeform rotationally asymmetric shapes of the first surface, the second surface, the third surface, and the mirror surface are configured to together correct for distortion in the projected image, wherein the freeform rotationally asymmetric shapes are configured to increase a field of view of the projected image while maintaining a ratio of spot size to ideal pixel size, and wherein the mirror surface is further configured to reduce chromatic aberration in the projected image.
