Abstract:
1. A scanning platform, comprising: a scanning mirror disposed in a scanning body via a mirror flexure; and an outer frame supporting the scanning body and the scanning mirror via a first flexure, the outer frame being supported in a fixed body via a second flexure, the scanning body and the outer frame having a first set of comb fingers disposed thereon to cause the scanning body to oscillate about a first axis via torsion or other deflection of the first flexure in response to a first drive voltage applied to the first set of comb fingers, and the outer frame and the fixed body having a second set of comb fingers disposed thereon to cause the outer frame to oscillate about a second axis via torsion or other deflection of the second flexure in response to a second drive voltage applied to the second set of comb fingers; wherein the scanning mirror oscillates about the first axis via oscillation of the scanning body, and the scanning mirror oscillates about the second axis via oscillation of the outer frame that excites resonant motion of the scanning mirror about the mirror flexure via mechanical coupling of the scanning mirror with outer frame to result in a two-dimensional scanning pattern resulting from the first drive voltage and the second drive voltage.
