Description
technical field [0001] The invention relates to the technical field of beam control, in particular to a two-dimensional fast-swing reflector and a working method thereof. Background technique [0002] Fast yaw mirrors are a type of key components in modern opto-mechanical systems. Their main function is to realize the angle pointing, scanning and stabilization of light by adjusting their mirror angles in real time. They have been widely used in space laser communication, autonomous Adapt to optics, compound axis precision tracking, astronomical telescope, laser imaging radar, laser beam stabilization system, confocal microscope, laser scanning and other fields. For example, in the space laser communication system, the fast deflection mirror is used to adjust and control the beam in real time, which can ensure the stability of the laser communication link. In the adaptive optics system, the fast yaw mirror adapts to changes in external conditions by continuously adjusting th...
