|Abstract:||A micro-sized 2-DOF grating laser scanner which is made to vibrate in-plane by an electrical comb-driven circular resonator drive is fabricated and tested. The frequency response of the prototype scanner in atmosphere to different driving voltages and the variations of its natural frequency with scanning amplitude are measured. The results are compared with those from finite element simulations using a comprehensive dynamic model, including the effects of geometric nonlinearity of the flexural beams under large deformations. The comparison shows that the predictions made by the developed nonlinear model are generally valid. © 2010 SPIE.|
