Abstract
An optical element can be adjusted using a displacement element in an actuator assembly. The actuator assembly includes a plurality of lead screws and a mechanical linkage configured to simultaneously rotate the lead screws. The actuator assembly further includes a displacement element configured to act upon the optical element, through translational motion of the displacement element in response to rotation of the lead screws. Multiple optical elements can be adjusted simultaneously using respective displacement elements. In some embodiments, a controller determines a target position for at least one displacement element, where the target position is configured to provide a desired optical characteristic such as an optical power. The controller can apply power to the actuator to move the at least one displacement element. The controller can also shut off power upon detecting that the at least one displacement element has reached the target position or an end-of-travel position.
