Abstract: In the present invention, a mirror transducer assembly is comprised of a mirror assembly and a driver assembly. Both the mirror assembly and the driver assembly include a diaphragm portion surrounding an integral central post member. The central post members are rigidly coupled together to provide tandem translation movement along a central axis passing through the central post members. A pair of non symmetrical piezoelectric disks are positioned on opposite sides of the diaphragm portion of the driver assembly. The size of the piezoelectric disks are selected to achieve a selected temperature sensitivity of movement of said tandem central members along an axis passing therethrough.
