,尤其是涉及一种基于压电陶瓷技术的光学相位调谐器。
技术介绍
由于单个望远镜孔径过大给望远镜镜面加工和移动等方面带来了困难,因此很多科研工作者开始了对光学综合孔径技术的研究,这项技术就是用多个小口径的光学镜面或光学系统综合成大口径,通过光路、镜面的调整和相位匹配,使得通过各个子孔径的光在共同焦平面上满足同相位要求,从而实现光场的相干叠加,达到与通光口径相当的单一大口径系统的衍射分辨率。目前光学综合孔径技术已经成为增大望远镜口径、提高望远镜分辨率的一种重要手段。要想得到较高的角分辨率,必须要增加望远镜的孔径。实际上,光学调相器的难点在于相位控制与调谐。因为传统光学调相装置结构相对复杂,制造工艺更加繁琐。
