1. An optical element driving mechanism, comprising:
a first movable portion connected to a first optical element;
a fixed portion, wherein the first movable portion is movable relative to the fixed portion;
a first driving assembly driving the first movable portion to move relative to the fixed portion in a first dimension;
a first supporting assembly disposed between the first movable portion and the fixed portion, wherein the first movable portion moves relative to the fixed portion via the first supporting assembly;
a second movable portion comprising a first holder, wherein the first holder is connected to the first optical element;
a second driving assembly driving the second movable portion to move relative to the fixed portion in a second dimension;
a third movable portion comprising a second holder, wherein the second holder is connected to a second optical element;
a third driving assembly driving the third movable portion to move relative to the fixed portion in a third dimension; and
a main axis;
wherein the first optical element has a first optical axis, and the second optical element has a second optical axis;
wherein:
a movement in the first dimension is a translational movement along the main axis;
a movement in the second dimension is a translational movement along the first optical axis;
a movement in the third dimension is a translational movement in a direction that is perpendicular to the second optical axis or a rotational movement around a first rotational axis, wherein the first rotational axis is parallel to the second optical axis.
