计算机控制光学表面成形技术(CCOS)广泛应用于反射镜的研抛过程，其去除函数通常选用去除效率高、去除稳定的近高斯形函数，但在加工过程中容易出现边缘翘边现象，严重影响反射镜的加工效率和面形收敛率。针对CCOS研磨过程中出现的边缘效应问题，提出一种应用于多自由度机械手的无偏心加工技术，对无偏心工具头的去除函数进行了分析，采用控制变量法研究加工压力、磨头转速和驻留时间等工艺参数对去除效率的影响，并对无偏心盘修边效果进行了试验验证。结果表明，通过对加工压力、磨头转速、磨盘悬挂比以及加工区域等加工参数进行合理调控，无偏心盘可以对翘边进行有效去除，且加工后面形平坦，可以很好地解决边缘效应问题。最后，针对研磨阶段提出了新的工艺流程：采用有偏心修形和无偏心修边相结合的工艺加工方式，可以快速提高反射镜面形加工的收敛效率，实现高效、高精度加工。

Significant optical engineering advances at the University of Arizona are being made for design, fabrication, and construction of next generation astronomical telescopes. This summary review paper focuses on the technological advances in three key areas. First is the optical fabrication technique used for constructing next-generation telescope mirrors. Advances in ground-based telescope control and instrumentation comprise the second area of development. This includes active alignment of the laser truss-based Large Binocular Telescope (LBT) prime focus camera, the new MOBIUS modular cross-dispersion spectroscopy unit used at the prime focal plane of the LBT, and topological pupil segment optimization. Lastly, future space telescope concepts and enabling technologies are discussed. Among these, the Nautilus space observatory requires challenging alignment of segmented multi-order diffractive elements. The OASIS terahertz space telescope presents unique challenges for characterizing the inflatable primary mirror, and the Hyperion space telescope pushes the limits of high spectral resolution, far-UV spectroscopy. The Coronagraphic Debris and Exoplanet Exploring Pioneer (CDEEP) is a Small Satellite (SmallSat) mission concept for high-contrast imaging of circumstellar disks and exoplanets using vector vortex coronagraph. These advances in optical engineering technologies will help mankind to probe, explore, and understand the scientific beauty of our universe.
