Abstract: An adjustable optical mount is disclosed. The adjustable optical mount can include a base. The adjustable optical mount can also include a rotatable frame rotatably coupled to the base about an axis. The rotatable frame can be operable to support an optical element. Additionally, the adjustable optical mount can include a ramp operably coupled to the rotatable frame such that translational movement of the ramp relative to the rotatable frame causes rotation of the rotatable frame about the axis to facilitate adjustment of the optical element in a rotational degree of freedom.

Abstract: A system includes a plurality of actuators configured to provide forces to an actuatable member to actuate the member between a first position and a second position during an actuation mode. The actuators are also configured to return the member from the second position to the first position during a retrace mode. The system also includes a controller configured to control the actuators. The controller is configured to identify a back electromotive force (BEMF) of each of the actuators during the retrace mode. The controller is also configured to responsively provide control signals to drive the actuators such that the forces provided by the actuators to the member during the actuation mode are substantially equal.
