    Abstract: An optical element driving mechanism is provided. The optical element driving mechanism includes a first holder, a second holder, a plate, a biasing assembly, and an electromagnetic driving assembly. The first holder holds a first optical element with a first optical axis. The second holder holds a second optical element with a second optical axis. The plate is disposed below the first holder and the second holder. The biasing assembly forces the first holder to move relative to the plate on a plane substantially perpendicular to the first optical axis, and includes a biasing element, wherein when a driving signal is applied to the biasing element, a length of the biasing element is changed. The electromagnetic driving assembly forces the second holder to move relative to the plate and comprising a first magnetic element and a coil.

    Abstract: An optical mechanism is provided. The optical mechanism includes a fixed member, a movable member, an optical element, a first sensing magnet and a first sensing element, wherein the movable member is movably connected to the fixed member, and the optical element is disposed on the movable member. The first sensing magnet corresponds to the optical element and has a first magnetic polar direction. The first sensing element corresponds to the first sensing magnet for detecting the rotation of the first sensing magnet around a first axis direction relative to the fixed member, wherein the first axis is perpendicular to the first magnetic polar direction.
