Abstract
A distally-actuated scanning mirror includes: a mirror block with reflective surface on one side; torsional hinges with proximal ends rigidly attached to the mirror block, and with distal ends attached to flexural structures configured to transform translational motion of the piezoelectric elements into rotational motion of the distal ends of the hinges; and piezoelectric elements providing such translational motion. The distally-actuated scanning mirror also includes flexural structures made of separate flexures attached to the opposite surfaces of the distal ends of the hinges, which flexural structures have defined thinned-down flexural points. Portions of the distally-actuated scanning mirror may be 3D printed and/or fabricated by silicon MEMS technology. The mirror is fabricated from a Silicon-on-Insulator wafer, having a relatively thick (e.g., 380 um) handle layer, and a relatively thin e.g., 50 um), where photolithography with backside-alignment allows separate patterning of these two layers.
