    Abstract: A driving mechanism for an optical element is provided, including a fixed portion, a movable portion, a first driving assembly, and a positioning assembly. The movable portion is movably disposed on the fixed portion, and includes an optical element. The first driving assembly is at least partially disposed on the fixed portion, and drives the optical element to move in a first direction. The positioning assembly is disposed on the fixed portion or the movable portion, wherein the positioning assembly limits the movable part to a first terminal position or a second terminal position relative to the fixed portion.

    Abstract: An optical system is provided and includes a light-sensing element, a reflecting unit and a first driving assembly. The reflecting unit includes a reflecting surface, configured to receive an incident light and to reflect a reflecting light. The reflecting light travels into the light-sensing element. The first driving assembly is configured to control the reflecting unit to move along a first axis direction from a first position to a second position, so as to adjust a focus position of the reflecting light on the light-sensing element, wherein the reflecting surface in the first position is parallel to the reflecting surface in the second position, and a distance between a center of the reflecting unit in the first position and the center of the reflecting unit in the second position is not zero.

    Abstract: A distance measuring device for measuring the distance to an object is provided, including a light-emitting module, a driving assembly disposed in the light-emitting module, and a light-receiving module. The light-emitting module has a housing, a light source disposed in the housing, a light grating element, and an optical path adjuster. The light source emits a measuring light through the optical path adjuster and the light grating element. The driving assembly can drive the optical path adjuster or the light grating element to move relative to the housing. The light-receiving module receives the measuring light which is reflected by the object to obtain distance information of the object.

    Abstract: An optical element driving mechanism includes a fixed assembly, a movable assembly, a driving assembly and a circuit assembly. The driving assembly is configured to drive the movable assembly to move relative to the fixed assembly. The driving assembly includes a first coil group which has a plurality of first coils and a magnetic module which has a magnetic element and a first conductive element. The circuit assembly includes a first circuit member electrically connected to the first conductive element and a second circuit member electrically connected to the first coils. When the magnetic module is located in different positions relative to the first coil group, the first conductive element is electrically connected to different first coils in sequence, so that the first coil is electrically connected to the first circuit member and the second circuit member, and other first coils remain open.
