1. An optical system, comprising:
a first optical module, including a first connecting member for connecting a first optical element;
a second optical module, including a second connecting member for connecting a second optical element; and
a fixed member,
wherein the first optical module and the second optical module are arranged in a first direction,
wherein the first optical module further includes a first driving assembly, a first movable assembly and a first fixed portion, and the first driving assembly is configured to drive the first movable assembly to move relative to the first fixed portion, so that the first movable assembly is in contact with the first optical element via the first connecting member,
wherein the first optical module further includes a position sensing assembly configured to sense movement of the first movable assembly relative to the first fixed portion, and the position sensing assembly includes a sensed unit and a sensing element, the sensing element corresponds to the sensed unit, wherein the sensed unit has a plurality of reference magnetic elements arranged in the first direction, the sensed unit and the sensing element are arranged in an arrangement direction, and the first direction is not parallel to the arrangement direction,
wherein the first optical module and the second optical module are fixedly disposed on the fixed member, and
wherein the fixed member is different from the first fixed portion of the first optical module.
