| 摘 要： | 介绍了平台间光路耦合传输系统的构成及光轴稳定控制的实现方法，开展了耦合校正系统和探测控制系统的设计，对校正系统进行了动态范围和模态仿真，优化设计后研制出光束耦合传输与控制系统。在对快反镜性能参数测试之后，开展了平台间光束耦合传输与控制实验，当振动台加载0 db振动谱且控制系统开环时，光轴X轴抖动10.9″@RSM，Y轴抖动102.3″@RSM，闭环时，光轴X轴抖动0.75″@RSM，Y轴抖动1.11″@RSM，通过频谱分析发现，快反镜光轴耦合系统闭环时对28 Hz以内光轴抖动具有较好地抑制作用，在系统开环残差较大的频率段2～6 Hz的抑制比为?40～?30 dB。实验结果表明，该光轴耦合控制系统对平台间光束传输过程中光束抖动具有较好地抑制和稳定效果。

| Abstract: | The structure of optical path coupling transmission system between platforms and the realization method for optical axis stability control are introduced in this paper. The coupling correction system and detection control system are designed, and the dynamic range and modal simulation of the correction system are carried out, followed by the developent of the beam coupling transmission and control system after design optimization. After testing the performance parameters of the fast mirror, we carried out the platform coupling transmission and control experiments. When the shaking table was loaded with 0 dB vibration spectrum and the control system was open-loop, the X-axis jitter was 10.9″@RMS and the Y-axis jitter was 102.3″@RMS. When closed-loop, the X-axis jitter was 0.75″@RMS and the Y-axis jitter was 1.11″@RMS. Spectrum analysis shows that when the fast mirror optical axis coupling system is closed-loop, it has a good suppression effect on the optical axis jitter within 28 Hz. The suppression ratio is from ?40 to ?30 dB in the frequency range of 2～6 Hz with large open-loop residual error. The experimental results prove that the optical axis coupling control system has a good effect of suppressing and stabilizing the beam jitter in the process of beam transmission between platforms. |
