Description
Technical Field
The invention relates to the technical field of photoelectric scanning and tracking, in particular to a moving magnetic actuating device for a large-aperture fast reflecting mirror.
Background
The fast reflector is a part working between a light source or a receiver and a target and used for adjusting and stabilizing the visual axis or the light beam pointing direction of an optical system, the deflection direction of the reflector is accurately controlled by adopting a voice coil motor so as to accurately control the deflection angle of the light beam, the fast reflector is used for realizing the fast adjustment of the 'deflection-inclination' azimuth angle of the reflector, and the fast reflector can be used for the visual axis stabilization or the scanning compensation in the field of photoelectricity and the like. The device has the advantages of compact structure, high response speed, high working bandwidth, high pointing precision and the like, is widely applied to the fields of astronomical telescopes, adaptive optics, image motion compensation, free space optical communication, precision tracking and the like, and becomes a key device for stabilizing light beams and correcting the propagation direction of the light beams in an optical system.
An important index of the fast reflecting mirror is the operating bandwidth, and the device influencing the index is the motor therein, which has to have higher output and shorter step response time. The traditional fast reflecting mirror generally comprises four motors, two motors are adopted to form a push-pull type pair in each rotating shaft direction, smooth and uniform torque is provided for the reflecting mirror, the output of the motors is not ideal, and the moving magnetic type actuating assembly used on the large-caliber fast reflecting mirror can greatly improve the output of the motors.
The existing voice coil motor equipped on the fast reflector is mostly designed in a moving coil mode as a driver, namely, a magnetic cylinder part is connected to a base of the fast reflector, and a coil is connected to a reflector support. Because the weight of the general coil part is far less than that of the cylinder part, the design can reduce the moment of inertia of the rotating part of the reflector, but the coil can generate more heat during working, and the heat can be transmitted to the reflector to cause the thermal deformation of the reflector, thereby reducing indexes such as the planeness of the reflector and the like, and further reducing the overall performance of the quick reflector. Some fast mirrors using a voice coil motor as a driver mostly use a cylindrical voice coil motor, and this type of voice coil motor has relatively high power output efficiency, but has a disadvantage that a gap between a coil and a cylinder is small, so that a rotation range of the fast mirror is small. And the electric output magnitude and the output efficiency of the existing moving magnet type voice coil cannot meet the requirement of higher and higher working bandwidth of the fast reflector.
