Problems solved by technology

The fast mirror is a lens mounted on the fulcrum driven by the piezoelectric ceramic stack, so that it can realize pitch and yaw motions. FSM has a large working bandwidth of about 150Hz, but it is also restricted by the swing range (piezoelectric ceramic type about 15urad), while the adjustment bandwidth of the follow-up turntable is small, but the adjustment range is large, and they can match each other to achieve fast and precise adjustment of the optical path

Abstract

The invention discloses a coarse-fine tracking experiment turntable carrying a fast steering mirror, which is characterized in that a fast steering mirror platform, a light passing hole, a pitching rotating beam, a pitching turntable rotating pivot and a pitching closed-loop stepping motor are sequentially connected, the pitching rotating beam is connected with an adapter base through a first bracket, a second bracket and a right-angle bracket, the fast steering mirror platform is provided with a fast steering mirror, a laser head clamping base and a laser head, the pitching rotating beam is sequentially provided with a pitching rotating platform upper adapter plate, a 45-degree reflecting base, a reflecting mirror, a CCD and laser range finder right-angle bracket, a CCD camera and a laser range finder, an azimuth adapter plate is arranged below the adapter base, an azimuth turntable rotating pivot is arranged below the azimuth adapter plate, and the azimuth turntable rotating pivot is provided with an azimuth turntable communication control interface and an azimuth closed-loop stepping motor which are connected with an external control device. The coarse-fine tracking experiment turntable can be applied to experiments for an indoor coarse-fine following control system, and has the characteristics of small volume, convenience and flexibility.

Description

technical field [0001] The patent of the present invention relates to the field of follow-up control, in particular to a coarse-fine composite follow-up experimental turntable equipped with a fast mirror. Background technique [0002] In order to improve the control accuracy in the servo control system, it is necessary to introduce a Fast Steering Mirror (FSM) with small inertia, high precision and fast response into the pitching turntable with large inertia, wide bandwidth, slow response and large tracking range. Coarse-fine composite follow-up system to improve the accuracy and bandwidth of the tracking and targeting system, and enhance its anti-disturbance ability and stable tracking ability. The fast mirror is a lens mounted on the fulcrum driven by the piezoelectric ceramic stack, so that it can realize pitch and yaw motions. FSM has a large working bandwidth of about 150Hz, but it is also restricted by the swing range (piezoelectric ceramic type It is about 15urad), w...
