| 摘 要： | 为了满足未来高精度光电稳瞄系统rad级稳定精度的测试需求，提出一种基于干涉仪测量的稳定精度测试方法。基于泰曼格林干涉仪中同源两光束光程差对干涉条纹的影响，利用CCD观察干涉条纹的微小变化，实现稳定精度测试。采用该测试方法对快速转向镜（fast steering mirror，FSM）的指向精度和某型光电稳瞄产品稳定精度进行了测试研究，结果表明，该方法对稳定精度的测量精度可以达到0.2 rad。

| Abstract: | In order to meet the testing need of rad level stabilization accuracy of high-precision EO stabilized sighting system in future,a method for testing the stabilization precision based on interferometer was proposed. According to the influence of the optical path difference of the two beams with the same source in the Twyman-Green interferometer on the interference fringe,the slight change of the interference fringe was observed utilizing the charge coupled device (CCD),as a result, the measurement of the stabilization precision was realized. By utilizing this measuring method, the aiming precision of the fast steering mirror (FSM) and the stabilized precision of a certain type of EO stabilized product were measured . Results show that the measurement precision can achieve 0.2 rad with our method. |
