Paper Abstract

The laser tracking measurement for space moving targets is the research hotspot in the precision measurement field, which has attracted many researchers' interests for many years. The tracking mechanism characterized with the performance of high accuracy and rapid response is the key to solving the dynamic measurement problem. In the paper, a project with one prism rotating around the rotating axis to attain the linear tracking is proposed, which can not only meet the requirements of the large range, rapid response and dynamic tracking, but also achieve the high accuracy of submicroradian magnitude due to the particular opto-mechanical design. Steering the tracking mechanism can well track the linear motion of space dynamic or static target. In order to study the above system, the technical parameters of the mechanism are firstly designed, and then the model analysis and simulation calculation is respectively carried out. Therefore, a new measurement is finally brought about, which points outs a solution for the measurement of space moving target with large range and high accuracy. The design results show the tracking accuracy is better than 0.5 μrad within the tracking angle range.
