Abstract
A mirror device and a method for audio feedback of a MEMS mirror device are presented. The mirror device includes a mirror with a reflective surface located to intercept a modulated beam of light produced by a laser. The mirror oscillates on a hinge axis structure A microphone detects the mirror oscillation information. The mirror device further includes a mirror driver system and a video controller system. The mirror driver system causes the mirror to rotate about the hinge axis structure. The video controller system uses the information received from the microphone, and the information received from the mirror-driver controller, to control the output of the laser.
