提出了完成大口径镜面的多孔径拼接技术,即利用实时相位探测技术实现尺寸小、精度高的子孔径镜面之间的位相合成,从而获得性能优越的大口径镜面。然后对多孔径拼接技术原理进行了较为详细的数学描述,并完成了原理性实验,最后获得了实验结果。

The subaperture alignment technique for large aperture mirrors is presented. Wavefront sampling technique is employed to achieve the coherent combination of segmented mirrors, which have much smaller aperture but with higher surface quality. Hence larger aperture mirror with good performance can be obtained in this way. The mathematic descriptions of subaperture alignment technique are given. A demonstration experiment was done and the results were obtained.
