Description

technical field [0001] The invention relates to the technical field of precision optical-mechanical structure design, in particular to a reflector structure suitable for telescopes, adaptive optics, laser communication, precise tracking and aiming, and stable optical paths. Background technique [0002] Due to the fast response speed and high control precision, the fast control mirror has become a key part of the optical system to stabilize and correct the beam. It has been widely used in the fields of telescopes, adaptive optics, laser communication, precision tracking and aiming. Its main performance indicators include Tracking range, resonant frequency and aperture of loadable mirrors. In the fast mirror structure, the structural form and driver directly determine the resonant frequency and load capacity of the system, which in turn affects the light aperture and response speed of the loadable mirror. Its main performance parameters restrict each other, and when determin...
