Abstract
An optical element driving mechanism is provided. The optical element driving mechanism includes a movable portion, a fixed portion, a magnetic sensed assembly, a first sensing element, and a magnetically permeable element. The movable portion is connected to an optical element which corresponds to incident light. The movable portion is movably connected to the fixed portion. The magnetic sensed assembly includes a first sensed portion having a first magnetic polar direction. The first sensing element is corresponding to the magnetic sensed assembly and is used to detect the rotation of the movable portion relative to the fixed portion, with a first rotational axis extending in a first direction that is different from an incident direction of the incident light and the first magnetic polar direction. The magnetically permeable element is corresponding to the first sensing magnet.
