Abstract
Techniques for adjusting an optical element using an actuator assembly. The optical element is adjusted by translating the optical element along a linear axis of motion or by applying force upon a surface of the optical element. The optical element can be a liquid lens that is shaped by the application of force upon a surface of the lens. The actuator assembly includes a plurality of lead screws and a mechanical linkage that intercouples the lead screws and that is configured to simultaneously rotate the plurality of 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 coupled to the lead screws.
