ABSTRACT:
A mirror transducer substrate apparatus for mounting a light reflecting apparatus has outer walls of nonuniform thickness. The substrate apparatus has a mirror side and a driver side, the mirror side includes an optical surface. The optical surface includes a first trepan formed therein having a first radial dimension. The driver side includes a second trepan formed therein having a second radial dimension which is larger than the first radial dimension. The first and second trepans are structured and arranged to form a nonuniform outer wall integral with the substrate apparatus and a first central post member, integral with the substrate apparatus, having a driver side, a mirror side which is coplanar with the optical surface, and a central axis passing therethrough. A first flexible annular diaphragm area is affixed to the driver side of the substrate apparatus covering the second trepan. A force applied against the first flexible annular diaphragm area causes the central post to move substantially linearly with a selected temperature sensitivity of movement along the central axis in the direction of the applied force.
