摘要

A dual axis, rester-scanning laser display based on a monolithic micromachined scanning mirror is presented. The scanner consists of a micromirror located at the end of a thermally actuated bimorph beam. The novelty of the device is that an "L"-shpae cantilever, which is simultaneously excited at non-resonance (frame scanning) and at resonance (raster scanning), gives the two orthogonal angular motions. The high sensitivity of th ethermal bimorph actuator allows a low frequency (non-resonant) movement of the scanner in one direction. The second orthogonal scanning direction is a resonance torsion motion.
