Fast reflector electric control system for improving pointing accuracy of laser emission system

Abstract

The invention provides a fast reflector electric control system for improving the pointing accuracy of a laser emission system, and relates to the field of fast reflector control. The fast reflector electric control system solves the problem that an existing control system cannot effectively improve the pointing accuracy of a laser emission system. The fast reflector electric control system comprises a main control computer, a servo controller connected with image processing software and an azimuth and elevation encoder in an infrared camera and a driver. The servo controller receives control instructions of the main control computer to execute corresponding actions, feeds tracking errors, positions and state data back to the main control computer, meanwhile receives data of the azimuth and elevation encoder to perform digital computation to output PWM signals, and receives image target-missing quantity data of the image processing software to control a fast reflector to perform real-time tracking. The driver is connected with the servo controller and an azimuth and elevation voice coil motor, amplifies the PWM signals to convert the PWM signals to be in a double-H-bridge PWM mode, and outputs motor control signals to control running of the motor. The fast reflector electric control system is high in control accuracy and easy to operate.

Description

technical field [0001] The invention relates to the technical field of fast mirror control, in particular to an electronic control system for a fast mirror used to improve the aiming accuracy of a laser emission system. Background technique [0002] Fast-Steering Mirror (FSM for short) is a precision tracking technology that has been widely used in laser emission systems to improve laser aiming accuracy. At present, the most researched fast mirrors mainly have two structural forms: one is the X-Y axis frame type, also known as the shaft type, which has good structural rigidity, strong bearing capacity and large rotation angle range; the other is flexible shaftless The structure mainly utilizes the flexibility of the elastic element to work. [0003] The main body of the X-Y axis frame-type fast mirror is in the form of an inner and outer frame structure. The inner and outer frames rotate around two mutually orthogonal axes respectively. The outer frame controls the azimuth ...
