| 摘 要： | 本文介绍在怀柔６０ｃｍ多通道太阳望远镜上运用斑点干涉像复原方法所取得的一些初步结果,对用短暴光方法（暴光时间不大于１０毫秒）获得的一系列“冻结”大气后的目标像用斑点干涉像复原方法进行处理,即可获得消除了地球大气影响的目标复原像,斑点掩模法即为斑点干涉像复原方法的一种,我们用它对日面中心的宁静区米粒进行处理,复原出了分率不劣于０．〃５的白光米粒象。

| Abstract: | In this article, we introduce some preliminary results obtained by the method of speckle interference image recovery in Huairou's 60cm Multi-Channel Solar Telescope. When the atmosphere turbulence of the earth is "frozen" by the means of short exposure (the exposure time is not longer than 10 milliseconds),we collect a sequence of images of a solar object. Then,by the method of speckle interference image recovery,the atmosphere effect on these images may be removed and the reconstructed images of the solar object obtained.We have used Speckle-Masking method,one of the speckle interference method,to process the solar granulation in the quiet region near the disk center and reconstructed some white light granular images with resolution not worse than 0.5 arcsec. |
