Abstract
A mirror system comprising: a mirror; at least one piezoelectric motor having a coupling surface for coupling the motor to a moveable body; at least one spherical contact surface coupled to the mirror; and a motor mounting frame that holds a piezoelectric motor of the at least one piezoelectric motor and presses the piezoelectric motor coupling surface to a contact surface of the spherical contact surface; wherein the motor is controllable to apply force to the contact surface that rotates the mirror.
