When it comes to fast mirrors, many people are unfamiliar with them because they are always hidden in the "body" of an optical precision tracking control system, playing an important role in silence. 

     Yes, fast mirrors play an important role, such as long-distance laser communication, adaptive optics, Space Telescope Systems and other optical systems on its own, and its infiltration to spacecraft, aircraft, cars and other sports platform. 

      So why do these platforms introduce fast mirrors? Naturally, it is because of some advantages it brings. It is learned that the disturbance on the moving carrier is of wide frequency band, and the anti-disturbance ability of the traditional control method is limited, so it can not meet the high requirement of stable control, the disturbance of the base on the moving platform can be directly transmitted to the mirror surface of the fast mirror, which reduces the tracking accuracy of the deflection beam and greatly degrades the performance of the system. 

    Speaking of fast mirrors, the voice coil motor is closely related to it. The voice coil motor fast mirror adjusts the light path through the two axes of the mirror to compensate for the effect of the vibration on the light path, or to control the light path to produce the desired direction. The fast mirror of the voice coil motor is driven by the precision voice coil motor which has been specially designed, with large output force, fast response and high control precision, and the integrated design technology of the mirror and supporting structure is adopted to reduce the MASS/INERTIA and the volume, it has excellent dynamic characteristics and adopts the optimization technology of rotating shaft configuration to make the fast mirror have good control accuracy and closed-loop bandwidth. 

      Kunshan has been working in the field of voice coil motor for more than 10 years. The voice coil motor adopts the European and American technical standards and processing technology.
