Abstract
The translation device includes first and second plates, one movable relative to the other in response to a plurality of piezoelectric transducers. A flexure is located between the first and second plates and attached to each of them to spring-load the piezoelectric transducers. The driver circuit produces voltages which are balanced and applied to the piezoelectric transducers to produce tilt-free translation of the first plate relative to the second.
