摘要： This application provides a zoom lens group, a camera apparatus, an electronic device, and a zoom method. The zoom lens group is disposed on an object side of an imaging lens group along a direction of an optical axis, the zoom lens group includes an optical element and a drive element, and the drive element is configured to drive the optical element to move along a first direction, so that the optical element cuts into or moves out of an optical path, to implement zoom. The first direction is set at an included angle with the optical axis, and the optical path may be understood as a position at which the optical axis is located. In this application, the zoom lens group is disposed on the object side of the imaging lens group, and the optical element cuts into or moves out of the optical path, so that not only zoom can be implemented, but also a relatively large field of view can be obtained in a state in which the optical element cuts into the optical path.

摘要： A scanning module, a detection apparatus, and a terminal device are provided to resolve a problem of low detection accuracy in the conventional technology. This application may be applied to the fields such as autonomous driving, intelligent driving, and assisted driving. The scanning module includes m reflective surfaces that are of a polyhedron reflective component and that are adjacent in a first direction, where m is a positive integer. For a first reflective surface in the m reflective surfaces, the first reflective surface includes n reflective sub-surfaces, and an included angle between two adjacent reflective sub-surfaces is greater than 0° and less than 180°, where n is an even number greater than or equal to 4, and the n reflective sub-surfaces are adjacent in a second direction different from the first direction. Because detection light emitted to two adjacent reflective sub-surfaces is converged after being reflected by the two reflective sub-surfaces, a size of a light spot of the detection light reflected by the scanning module can be reduced, to reduce or even eliminate stray light reflected by another mechanical part or the like due to a large size of the light spot of the detection light, so that accuracy of the detection apparatus using the scanning module can be improved.
