摘要
为使拼接式望远镜的分辨率接近等效口径的衍射极限,各子镜必须具有极高的共面精度。针对拼接式望远镜的共相问题,首先,研究了拼接式望远镜光学共相探测中瞳面共相探测技术和焦面共相探测技术的原理。然后,总结了各项光学共相探测技术的优缺点、适用领域以及未来发展趋势。最后,分别为大平移误差、大倾斜误差的探测问题提供了解决方案。
In order to make the resolution of segmented telescopes close to the diffraction limit of equivalent aperture,each sub-mirror must have extra high coplanar precision.In this paper,aiming at the co-phasing problem of segmented telescopes,first,the principle of co-phasing detection technology of pupil plane and focal plane in segmented telescopes optical co-phasing detection technology is studied.Then,the advantages and disadvantages,application fields and future development trends are summarized.Finally,solutions are provided on the detection problems of large piston error and large tip-tilt error respectively.
