摘　　要：对于大型光学望远镜来说,主次镜之间的相对位姿有着非常严格的要求,由于主镜质量较大,因此常常将次镜系统设计为有多个自由度的可调整机构,其调整效果对望远镜成像有着重要的影响。随着望远镜的口径不断增大,应用场景的不断发展,次镜调整机构不止要保证高精度,还要有高负载,其设计也越来越具有挑战性。为了寻找大口径望远镜次镜调整机构的可行方案,针对大型光学望远镜的次镜调整机构的发展需求和不同的应用情况,对不同的次镜调整机构进行了整理,分类和对比,最后对各种次镜调整机构的优势与不足进行了总结,对大口径望远镜未来的发展进行了展望。For large optical telescopes,the relative poses between the primary and secondary mirrors have very strict requirements.Due to the large quality of the primary mirror,the secondary mirror system is often designed as an adjustable mechanism with multiple degrees of freedom.It has an important impact on telescope imaging.As the diameter of the telescope continues to increase and the application scenarios continue to develop,the secondary mirror adjustment mechanism must not only ensure high precision,but also have a high load,and its design is becoming more and more challenging.In order to find a feasible solution for the adjustment mechanism of the secondary mirror of the large-aperture telescope,according to the development needs and different applications of the adjustment mechanism of the secondary mirror of the large-scale optical telescope,the different adjustment mechanisms of the secondary mirror are sorted,classified and compared.The advantages and disadvantages of the secondary mirror adjustment mechanism are summarized,and the future development of large-aperture telescopes is prospected.
