The light is incident to a light-path adjustment element via an incident axis, and travels into the optical element driving mechanism along a first axis, and the incident axis is not parallel to the first axis. The optical element driving mechanism includes a movable portion, a fixed portion, and a driving assembly. The movable portion has a receiving space configured to connect an optical element. The fixed portion includes a base, the movable portion is movable relative to the fixed portion, and the base has a first surface facing the movable portion. The driving assembly is configured to drive the movable portion to move. The movable portion further includes an opening connected to the receiving space, and when viewed along the first axis, the sidewall of the optical element is located between the opening and the first surface.

Abstract: An optical system is provided and includes a fixed module, a movable module, a driving coil, a sensing unit and a driving assembly. The fixed module includes an outer frame, and the movable module includes an optical member holder, configured to hold an optical member. The sensing unit is configured to obtain information related to a first rotation angle of the optical member holder when rotating around a first axis relative to the outer frame and a second rotation angle of the optical member holder when rotating around a second axis relative to the outer frame. The driving assembly is for driving the optical member holder to rotate around the first axis or the second axis according to the information related to the first rotation angle and the second rotation angle. The first axis or the second axis is perpendicular to an optical axis of the optical member.
