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 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.

Abstract: A camera system including a telephoto lens module is provided. The telephoto lens module includes a first image sensor, a first assembly, and a second assembly. The first assembly includes a first driving mechanism and a reflecting member connected to the first driving mechanism. The first driving mechanism is configured to drive the reflecting member to rotate around a first axis and a second axis. The second assembly is disposed between the first assembly and the first image sensor, including a second driving mechanism and a first lens. The second driving mechanism is configured to drive the first lens to move along a third axis. The first, second, and third axes are not parallel to each other. When light enters the telephoto lens along the first axis, light is reflected by the reflecting member and through the first lens along the third axis to the first image sensor.
