Embodiment Construction
[0020] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0021] like Figure 2 to Figure 4 As shown, this embodiment is composed of a stepping motor 5, a base 4, a screw transmission assembly 3, a flexible hinge 2 and a mirror platform 1, etc. The reflector 6 is fixed in the reflector frame 8 through three reflector pressing blocks 7 to form the reflector platform 1 . The stepper motor 5, the screw transmission assembly 3 and the flexible hinge 2 with two-dimensional deflection and translation flexibility constitute a set of drive assemblies. The three sets of drive components are arranged in an equilateral triangle. The stepper motors 5 of the three drive assemblies rotate according to the number of control pulses, and the screw drive assembly 3 converts the rotational motion of the stepper motors 5 into a linear push or pull action on the mirror platform 1 . When the two-dimensional deflection o...

The invention discloses an electrical adjusting mirror based on rotary motors and flexible hinges. The electrical adjusting mirror comprises a reflector platform, a base, the rotary motors, spiral transmission assemblies and the flexible hinges. One driving assembly is composed of one rotary motor, one spiral transmission assembly and one flexible hinge, and the reflector platform is connected with the base through the three driving assemblies. Each flexible hinge has two-dimensional deflection and translational flexibility, and the spiral transmission assemblies meet the self-locking requirement. Axial translation of a reflector can be achieved through synchronous rotation of the three rotary motors, and the two-dimensional rotation of the reflector can be achieved through driving of anytwo rotary motors. For light beams not in a 0-degree incidence mode, the electrical adjusting mirror can synchronously adjust the direction of the light beams and positions of faculae on the surface of the reflector in an incident plane of the light beams.
Description
technical field [0001] The invention relates to the technical field of beam control, in particular to an electric mirror based on a rotating motor and a flexible hinge, which can be used for two-dimensional deflection adjustment of a beam. Background technique [0002] In optical systems, the two-dimensional deflection adjustment of mirrors is a common requirement to meet the precise adjustment of the beam propagation direction. In some occasions, while adjusting the propagation direction of the beam, it is necessary to adjust the position of the spot on the mirror in the incident plane of the beam, such as figure 1 shown. Currently, two-dimensional fast mirrors are widely used for precise adjustment of light beams. However, in the occasions where there is no need to adjust the beam direction quickly and at high frequency, using fast mirrors to adjust the optical path is really overkill. Moreover, the fast mirror cannot realize the self-locking of the position. The Chine...
