【摘要】：目前太陽活動觀測存在視場小和分辨率低的問題。單共軛自適應光學系統(tǒng)可校正的視場范圍較小,多層共軛自適應光學系統(tǒng)使用三維重構的方法,耗時長且過程繁瑣;而太陽地表層自適應光學系統(tǒng)只校正地表層湍流,效率高,能快速獲得大視場、高分辨率圖像。利用YAO軟件,在四導星陣列分布情況下,應用平均算法對太陽,地表層自適應光學系統(tǒng)在40″和60″優(yōu)化視場、J和H波段的性能進行數值仿真,并與相同條件下仿真得到的單共軛自適應光學系統(tǒng)性能結果進行比較。結果表明,在60″~120″成像視場內,地表層自適應光學系統(tǒng)的斯特列爾比值比單共軛自適應光學系統(tǒng)提高了130%~210%,該結果與太陽自適應光學領域其他軟件得到的仿真結果一致。
[Abstract]:At present, the problems of small field of view and low resolution exist in solar activity observation. The single conjugate adaptive optical system has a small corrected field of view. The multilayer conjugate adaptive optical system uses the method of 3D reconstruction, which takes a long time and the process is tedious. However, the solar surface adaptive optical system only corrects the turbulence on the surface of the earth, so it can obtain large field of view and high resolution images quickly. With the help of YAO software, the average algorithm is used to simulate the performance of the solar and surface adaptive optical systems in 40 "and 60" optimal field of view, J and H bands. The results are compared with the simulation results of single conjugate adaptive optical system under the same conditions. The results show that in the field of view of 60 "~ 120" imaging, the Stryer ratio of the ground surface adaptive optics system is 130 ~ 210 higher than that of the single conjugate adaptive optical system. The results are in agreement with the simulation results obtained by other software in the field of solar adaptive optics.
