The invention provides a centroid-adjustable motion swing mirror mechanism which enables the centroid of a swing mirror to be independently adjusted in two dimensions so as to adjust the centroid of the swing mirror to a rotating shaft of the swing mirror, is simple in structure and convenient to operate, can greatly reduce vibration of the swing mirror in a scanning imaging system due to the factthat the rotating shaft does not pass through the centroid, and has good practicability. The device comprises the swing mirror, the rotating shaft, a circumferential adjusting rod and a counterweightsliding block; the non-reflecting surface of the swing mirror is fixedly connected with a connecting seat; the rotating shaft is installed on the connecting seat; the rotating shaft is pivoted relative to the installation position of the connecting seat; one end of the circumferential adjusting rod is fixedly sleeved on the rotating shaft; the counterweight sliding block is sleeved on the circumferential adjusting rod in the length direction; and a locking screw fixedly connected with the circumferential adjusting rod is arranged on the counterweight sliding block.
Description
technical field [0001] The invention relates to the technical field of filter equipment, in particular to a moving mirror mechanism with an adjustable center of mass. Background technique [0002] In the scanning imaging system, whether the oscillation of the oscillating mirror is accurate and stable directly determines the quality of the imaging. For the scanning imaging system, if the rotating shaft of the swing mirror can pass through the center of mass of the swing mirror, the vibration caused by the swing of the center of mass during scanning will be the smallest, so the image quality will be the best. However, under normal circumstances, due to the needs of mechanical installation, the rotation axis of the oscillating mirror often cannot pass through the center of mass of the oscillating mirror, but is close to the non-reflecting side of the oscillating mirror, or due to the limited space size of the scanning system, the rotating axis of the oscillating mirror is not l...
