Abstract: An optical system is provided and includes a fixed module, a movable module, a sensing unit and a driving assembly. The fixed module includes a base, and the movable module includes an optical member holder, configured to hold an optical member. The sensing unit is configured to obtain information related to a first rotation angle of the optical member holder when rotating around a first axis relative to the base and a second rotation angle of the optical member holder when rotating around a second axis relative to the base. The driving assembly includes a coil, the coil and the movable module are arranged along an optical axis of the optical member, and the coil is disposed around an opening of the base. The first axis or the second axis is perpendicular to the optical axis.

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 sequentially through the optical path adjuster and the light grating element along a first axis. 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: A multiple-lens camera system is provided, including a first lens driving module, a second lens driving module, and a shielding member. The first and second lens driving modules respectively include a frame, a lens holder movably disposed in the frame for holding a lens, a magnetic element disposed on a side of the lens holder and a driving board, wherein the driving board has a first coil corresponding to the magnetic element, to generate a magnetic force for moving the lens holder and the lens relative to the driving board. The shielding member is disposed in the first lens driving module and between the two magnetic elements of the first and second lens driving modules which are adjacent to each other, to suppress magnetic interference between the first and second lens driving modules.
