Abstract
An actuator including a frame body, a base, a first drive assembly, a second drive assembly, and an optical element is provided. The frame body includes the first frame portion and the second frame portion. The base surrounds the frame body. The first drive assembly is disposed between the base and the first frame portion. The second drive assembly is disposed between the base and the second frame portion. When the actuator is set to a first mode, a phase difference between the first drive assembly and the second drive assembly is substantially 0 degrees, and the optical element exhibits a first actuation mode relative to the base. Alternatively, when the actuator is set to the second mode, the phase difference between the first drive assembly and the second drive assembly is substantially 90 degrees, and the optical element exhibits a second actuation mode relative to the base.
