Abstract
In one aspect, a system for facilitating short depth projection is shown and described. In brief overview, the system comprises a MEMS scanner that produces a ray of light in communication with an illumination source. An oscillating micromirror receives the ray of light from the illumination source and reflects the ray to one or more points on a curved reflective surface. The micromirror comprises a silicon mirror reinforced by a high-stiffness material. The system further comprises a screen on which the curved reflective surface projects the ray of light received from the micromirror.
