Description

technical field [0001] The invention belongs to the technical field of space optical remote sensing, and in particular relates to an integrated two-dimensional actuator applied to the adjustment of the focal plane of a space optical camera. Background technique [0002] The spatial optical camera needs two-dimensional adjustment of the focus plane when taking pictures, that is, focus adjustment and bias current adjustment. High-precision image motion compensation can accurately image the target area on the photosensitive surface of the CCD, and it occupies a small space, is light in weight, and has sufficient strength, rigidity, good self-locking performance and anti-cold welding performance. [0003] The closest existing technology to the present invention is the research on the two-dimensional precision adjustment mechanism of the focal plane published by Chai Fangmao and others at the Changchun Institute of Optics, Fine Mechanics and Physics, Chinese Academy of Sciences i...
