Description

Positioning device and installation method of quick reflection mirror voice coil motor
Technical Field
The invention relates to the technical field of photoelectric tracking, in particular to a positioning device and a quick-reflection mirror voice coil motor mounting method.
Background
The quick reflector is a component which works between a light source or a receiver and a target and is used for adjusting and stabilizing the visual axis or the light beam direction of an optical system, and the deflection direction of the reflector is precisely controlled by adopting a voice coil motor so as to precisely control the deflection angle of the light beam. The optical system has the advantages of compact structure, high response speed, high working bandwidth, high pointing precision and the like, and is widely applied to the fields of astronomical telescope, adaptive optics, image shift compensation, free space optical communication, precise tracking and the like, thereby being a key device for stabilizing light beams and correcting the propagation directions of the light beams in an optical system. And the moving-magnet voice coil motor is adopted, so that the cable can be prevented from being dragged or broken, and the heat of the voice coil motor can be prevented from being transmitted to the reflecting mirror.
An important indicator of the fast mirror is the operating bandwidth, and the device affecting this indicator is the voice coil motor therein, which must have a high output and a short step response time. Conventional fast reflectors typically include four voice coil motors. Two voice coil motors are adopted to form push-pull pairs in the direction of each rotating shaft, so that smooth and uniform torque is provided for the reflecting mirror.
The existing voice coil motor is used as a quick reflector of a driver, and most of the voice coil motor adopts a moving coil type design, namely a magnetic cylinder part is connected to a quick reflector base, and a coil is connected to a reflector support. Since the weight of the coil portion is generally much smaller than that of the magnetic cylinder portion, such a design can reduce the moment of inertia of the rotating portion of the mirror, thereby achieving a relatively high operating bandwidth. However, two problems are brought, namely, the voice coil motor cannot adjust the positioning device, so that the cable is easy to break due to long-time movement; secondly, more heat can be generated when the coil works, and the heat can be conducted to the reflecting mirror to cause the thermal deformation of the reflecting mirror, so that the indexes such as the flatness of the reflecting mirror are reduced, and the overall performance of the quick reflecting mirror is reduced. Most of the existing quick-reflecting mirrors adopting voice coil motors as drivers adopt cylindrical voice coil motors, the voice coil motors of the type have relatively high output efficiency, but the disadvantage is that the gap between the coil and the magnetic cylinder is small and cannot be moved, so that the rotating range of the quick-reflecting mirror is small, the output size and the output efficiency of the existing moving-magnet voice coil motors cannot meet the requirements of increasingly high working bandwidths of the quick-reflecting mirrors, and the traditional voice coil motors cannot adjust and position, so that the performance of the whole device is unstable and the step wave occurs.
