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.
Abstract translation: 一种系统包括多个致动器，其构造成在致动模式期间向可致动构件提供力以致动构件在第一位置和第二位置之间。 致动器还构造成在回扫模式期间将构件从第二位置返回到第一位置。 该系统还包括被配置为控制致动器的控制器。 控制器被配置为在回扫模式期间识别每个致动器的反电动势（BEMF）。 控制器还被配置为响应地提供控制信号以驱动致动器，使得在致动模式期间由致动器提供给构件的力基本相等。

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.
