摘要
云南天文台1987年完成斑点干涉术研究后,即刻转入天文高分辨率二维像复原阶段的研究.在对斑点掩模法进行了真实大气、望远镜条件下的模拟实验之后,于1990年9月用该方法对两对双星做了实验,基本上得到了成功.这些实验表明,取样期间大气统计特性不变和小方差条件的重要性.为满足这一条件,合适的探测器是必须的.
Since the completion of research on speckle interferometry at the Yunnan Observatory in 1987, the studies of the high-resolution two-dime sional image reconstruction have been carried out. After the simulation test of the image reconstruction by the speckle masking under the conditions of the real atmosphere and telescope, the trial observations of two binaries with this method were successfully given in Sept. 1990. The results of these tests show the importance of the invariability and small variance of the statistical characteristics of the atmosphere during the sampling. Therefore, a suitable detector is necessary to meet the conditions.
