Claim 12:
13. A system comprising:
an optical engine configured to emit an elliptical light beam;
a first micro-electromechanical system (MEMS) mirror comprising an elliptical mirror plate and being configured to receive the elliptical light beam and to oscillate the elliptical mirror plate to reflect the elliptical light beam along a first scanning axis;
at least one shaping lens configured to receive the elliptical light beam reflected from the first MEMS mirror and configured to reshape the elliptical light beam to have a substantially circular cross-section to produce a circular light beam;
a second MEMS mirror configured to scan the circular light beam along a second scanning axis that is different from the first scanning axis; and
a controller configured to control a timing of emission of the elliptical light beam from the optical engine for modulating the elliptical light beam to be perceived as images when output at an output of the system.
