Abstract

The reflection process of the fast-steering mirror in an electro-optical tracking system was researched to improve its tracking precision. Firstly

the relationship of the turning angles between fast-steering mirror and reflection light was deduced

and the control method of the fast-steering mirror system was expatiated in detail as well as the software realization. Then

by taking the relationship mentioned above for the thesis

a servo control system for the fast-steering mirror was established. Furthermore

zero-locked and tracking experiments were performed to verify the performance of the control system

and the experimental results for the fast-steering mirror system and the main shafting system were compared. Obtained results indicate that the fast-steering system has fast-response and high-precision

and the residual error is less than 1" in the zero-locked experiment. Moreover

the Root Mean Square (RMS) error of azimuth tracking in the fast-steering system is 3.6" and the RMS error of elevation tracking is 8.7" in the tracking experiment

which meets the requirement of tracking system for the tracking speed and pointing precision. The conclusion is that the servo system for fast-steering mirror based on the thesis on reflection process is characterized by high precision and fast response.
