Such a telescope can be formed with an array of sub-telescopes in each of which an image of the observed area is recorded at the different.

提出了一种新型太阳光谱望远镜的建议,这种望远镜能够同时记录太阳日面观测区域的两维空间的色散(三维光谱),即一系列同步狭窄带通的光谱图像。

The optical correlation function is used to determine the correlation time of atmospheric turbulence, within the time the effect of atmospheric turbulence is taken into account by using the optical transfer function,finally,the optical quality of a large telescope system(with aperture of 500mm,focal length of 500m) is calibrated.

利用大气湍流的光学相关函数确定湍流光学相关时间，并在此时间内通过成像系统的光学传递函数修正大气湍流效应后定标大望远镜（５００ｍｍ口径，５００ｍ焦距）系统衍射极限倍数。

Now there are ten 8- 10m large telescopes have been used for science observation.

目前 ,已有 1 0架口径 8～ 1 0m的地面大望远镜建成并投入科学观测。
