ABSTRACT:
A dynamic mount and actuator for a laser mirror 20 comprising three layers of electroded piezoelectric wafers 46, adjacent layers being bonded. The one-axis movements of each shear motor 40 are amplified by and transmitted to an axially extending flex-joint assembly 36 which is formed with two universal-type flex joints 102,104 therein. A support member 34 coupled to the flex-joint assembly 36 extends from the front end thereof through the suspension ring holder 29, flexure assembly 28, suspension ring 26 and mirror-backing plate 24 and is fastened to the mirror 20 by an interface pin 30 which does not distort the mirror 20.
