Abstract: A lens driving module includes a reflecting element, a base, a frame, a holder, an optical lens, a first electromagnetic driving assembly, and a second electromagnetic driving assembly. The frame is connected to the base, and the holder holds the optical lens and movably connects to the base. The reflecting element reflects light from the outside along a light incident direction to an optical lens along a first direction, wherein the light incident direction is perpendicular to the first direction. The first and second electromagnetic driving assemblies force the holder to move relative to the base, wherein the first electromagnetic driving assembly has a first drive coil, the second electromagnetic driving assembly has a second drive coil, the first and second drive coils have elongated structures extending in a second direction and the first direction respectively, and the first direction is perpendicular to the second direction.

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.
