摘要

反射镜重新定位系统是大型可部署空间望远镜中的一个关键系统，有助于在部署后纠正反射镜方位的误差。由于斯图尔特机构具有在高精度应用中使用的潜力，因此采用它来调整反射镜的方向，并利用双分辨率致动器设计了一个用于定位反射镜的高范围、高精度斯图尔特平台。系统表征对于了解、优化和评估系统性能至关重要。它有助于深入了解系统的行为、优势、劣势和局限性，有助于故障排除、设计决策和质量保证。总之，它为确保系统在整个生命周期内的功能、效率和可靠性奠定了基础。我们讨论了描述镜像重新定位系统特性所采用的技术，以及减少系统误差所采用的方法。

Characterization technique for high-resolution mirror repositioning hexapod mechanism for space telescopes

The mirror repositioning system is one critical system in large-size deployable space telescopes that aids in correcting errors in mirror orientation once deployed. Stewart mechanism is employed for reorienting the mirror due to its potential for use in high-precision applications, and a high-range and high-accuracy Stewart platform for positioning the mirror was designed using dual-resolution actuators. System characterization is crucial for understanding, optimizing, and evaluating the performance of a system. It provides insight into a system’s behavior, strengths, weaknesses, and limitations, aiding in troubleshooting, design decisions, and quality assurance. Overall, it forms the foundation for ensuring the functionality, efficiency, and reliability of a system throughout its lifecycle. We discuss the techniques adopted for characterizing the mirror repositioning system and the methods employed for error reduction in the system.
