Description

Technical field [0001] The invention belongs to the technical field of optical and mechanical structures, and mainly relates to an airborne optical lens focusing mechanism. Background technique [0002] In an airborne environment, the focal length of an optical lens will change with changes in environmental factors such as temperature and pressure. The change of the focal length of the optical lens will change the position of the image plane, resulting in unclear imaging of the optical lens. Therefore, it is necessary to adjust the focal length of the optical lens through a precise and rapid focusing mechanism to ensure a clear image of the optical lens. [0003] At present, there are mainly two ways to adjust the focus of an optical lens. One way is to realize focusing by driving the imaging detector assembly by a driving system; the other way is to realize focusing by driving the optical lens assembly to move by a driving system. [0004] The commonly used drive system structure f...
