Abstract: An optical module is provided. The optical module includes a first optical element driving mechanism. The first optical element driving mechanism includes a first movable portion, a first fixed portion, and a first driving assembly. The first movable portion connects an optical path adjustment element. The optical path adjustment element is configured to change a transmission direction of incident light to a first direction that is different from the transmission direction. The first fixed potion is polygonal when viewed in the transmission direction. The first movable portion is movable relative to the first fixed portion. The first driving assembly drives the first movable portion to move relative to the first fixed portion. The first driving assembly comprises a shape memory alloy. The first driving assembly is located on a first side of the first fixed portion when viewed in the transmission direction

Abstract: An optical member driving mechanism is provided, including a fixed portion, a movable portion, and a driving module, wherein the movable portion is movably connected to the fixed portion and includes an optical member holder and a spacing member. The optical member holder can support an optical member and has a surface facing the optical member. The optical member can change the moving direction of an external light. The spacing member is disposed between the surface and the optical member, and a gap is formed between the surface and the optical member. The driving module can drive the movable portion to move relative to the fixed portion.

Abstract: A driving mechanism is provided, including a base unit, a frame, a holder, a first driving assembly, a sensing magnet, and a magnetic field sensor. The base unit has a polygonal structure. The frame is connected to the base unit. The holder is connected to the frame for holding an optical element, wherein the optical element defines an optical axis. The first driving assembly is disposed on the base unit and the frame, close to a first side of the base unit for driving the holder and the frame to move relative to the base unit along a horizontal direction perpendicular to the optical axis. The sensing magnet is disposed on the holder and close to a second side of the base unit, opposite to the first side. The magnetic field sensor is disposed on the base unit for sensing the sensing magnet.

Abstract: An optical device includes a main base, a rotation mechanism, a carrying base, and an optical element. The rotation mechanism is connected to the main base. The carrying base is connected to the rotation mechanism. The optical element is disposed on the carrying base, and configured to change the transmission direction of an incident light. By changing the length of a bias wire of the rotation mechanism, the carrying base is rotated relative to the main base about a rotation axis.
