Description
Technical Field
The utility model relates to a technical field of filtering equipment specifically is a motion swing mirror mechanism of adjustable barycenter.
Background
In a scanning imaging system, whether the swing of the oscillating mirror is accurate and stable directly determines the quality of imaging. For a scanning imaging system, if the rotating shaft of the oscillating mirror can pass through the mass center of the oscillating mirror, the vibration caused by the oscillation of the mass center is minimum during scanning, and the image quality can be best. However, in general, because of the requirement of mechanical installation, the rotating shaft of the oscillating mirror often cannot pass through the center of mass of the oscillating mirror but is close to one side of the non-reflecting surface of the oscillating mirror, or because of the space size limitation of the scanning system, the rotating shaft of the oscillating mirror is not located on the symmetrical surface of the oscillating mirror, as shown in fig. 1, both of the above two cases can cause the scanning imaging system to generate certain vibration due to the eccentricity of the oscillating mirror, which not only affects the imaging quality, but also shortens the service life of the scanning imaging system.
In general, if the rotating shaft passes through the mass center of the oscillating mirror, a dynamic balance tester is needed to test the rotating shaft, and the mass center of the oscillating mirror is moved to the rotating shaft by accurately balancing weights at the designated position of the oscillating mirror. This method requires special test equipment and various counterweights of different masses, which is costly and complicated to operate.
