摘要	To improve the pointing precision of output laser for a tracking turntable, the relationship between the attitude angles of a Fast Steering Mirror (FSM) and the tracking error of a tracking turntable was researched and a high precision calculation method for attitude control angles of the FSM was proposed. The light path of the output laser of the tracking turntable and the operating principle of the FSM were introduced. Then, the directions of the incident light and emergent light were determined in different coordinate systems and the functional relationship between the attitude control angles and the tracking errors was derived based on the coordinate transformation theory and the reflection law of light. Furthermore, the analytical expressions of the attitude control angles were obtained, and the space distribution characteristics of the attitude angle were explained. A set of approximation expressions of the attitude control angles were derived from the analytical expressions, and the extra pointing errors caused by the approximation expressions were studied. Finally, a pointing precision experiment was performed to verify the correctness of the formulas for calculating the attitude control angles. The experimental results show that both the analytical formulas and the approximation formulas guarantee the pointing error to be less than 2.5 with the turntable tracking errors less than (A 12.9', E 13.5'). However, the approximation formulas cause the pointing errors to grow to 13.2 and the turntable tracking errors to grow to (A 38.6', E 37.8') while the analytical formulas keep the pointing errors to be within 2.5. It demonstrates that as terse-form analytical formulas of the attitude control angles have no principle errors, it always can output the laser beam with high precision pointing ability under any turntable tracking errors, and they show simple forms and satisfy the requirement of rapid calculation of servo controllers. 2016, Science Press.
