A 3D object information capturing system is provided, including a camera module, a distance measuring module, and a processing module. The camera module captures image information of an object, and the distance measuring module captures distance information of the object. The processing module receives the image information and the distance information respectively from the camera module and the distance measuring module, and constructs a 3D model of the object according to the image information and the distance information.

An aperture device for setting an amount of light incident on a lens of a camera module is provided. The aperture device includes: a diaphragm plate exhibiting a plate shape and formed with an aperture opening penetrating the diaphragm plate in a plate surface direction; and a configuration-changing mechanism for changing a configuration of the diaphragm plate to an aperture position or a retracted position, where the aperture position is a position where the diaphragm plate is on the lens and a center of the aperture opening is configured in a position corresponding to an optical axis of the lens, and the retracted position is a position where the diaphragm plate is retracted from the lens.

The driving module can drive the movable portion to move relative to the fixed portion.

An optical system is provided, including a holder, a fixed module, a driving assembly, and a first resilient member. The holder is used for holding an optical element that defines an optical axis. The fixed module is movably connected to the holder and has a housing and a base connected to the housing. The base has a bottom surface parallel to the optical axis and a first pillar forming a first surface that is not parallel to the optical axis. The driving assembly drives the holder to move relative to the fixed module. The first resilient member is disposed on the first surface and movably connects the holder with the fixed module.

Night vision refocus devices are provided, in which the night vision refocus devices include a housing comprising (i) a proximate end configured to couple to a lens frame (e.g., housing an objective lens) of a night vision device and a distal end, (ii) a faceplate operably connected to the housing, in which the faceplate includes a faceplate aperture, and (iii) an aperture-selection component (ASC) rotatably mounted directly or indirectly to the faceplate. The ASC includes a plurality of individual refocusing-apertures (IFAs) including a first IFA having a first area and a second IFA having a second area, in which the first area is larger than the second area. The first IFA is aligned with the faceplate aperture when the ASC is oriented in a first position, and the second IFA is aligned with the faceplate aperture when the ASC is oriented in a second position.

An optical system is provided, including a movable part, a fixed module, a driving assembly, a position sensor, and an electronic element.
