Abstract: An optical element driving system is provided. The optical element driving system includes an optical element driving mechanism and a control assembly. The optical element driving mechanism includes a movable portion, a fixed portion, and a driving assembly. The movable portion is used for connecting to an optical element. The movable portion is movable relative to the fixed portion. The movable portion is in an accommodating space in the fixed portion. The driving assembly is used for driving the movable portion to move relative to the fixed portion. The control assembly provides a driving signal to the driving assembly to control the driving assembly. The driving assembly includes a first driving element, and the material of the first driving element includes shape memory alloy.

Abstract: A correction method for an optical mechanism having an optical member and a fixed portion is provided, including: an external apparatus measures the angle between the optical axis of the optical member and a reference surface of the fixed portion; the result of measuring the angle between the optical axis and the reference surface is compiled into data; the data is input into a control module; the control module transmits a signal to a driving module according to the data; and the driving module drives the optical member to rotate or move relative to the fixed portion upon receiving the signal. The optical mechanism does not include a sensor to detect the angle between the optical axis and the reference surface.
