中文摘要：

天文图像的高分辨率重建技术日益成为天文观测的一种手段。随着云南天文台丽江高美古2．4m望远镜的建立，基于2．4m望远镜利用高分辨率图像重建技术，对恒星系统中可能存在的暗弱伴星进行探测将成为一个现实的课题。本文拟通过实验和理论计算来论证，基于2．4m望远镜，利用天文图像的高分辨率重建技术，对恒星系统中可能存在的暗弱伴星在一定亮度范围内进行探测的可行性。

英文摘要：

High-resolution Image Reconstruction Techniques are increasingly becoming practical observational methods. With the setting up of the 2.4-meter telescope in Li-Jiang GMG, the detection of faint objects in multiple-star systems with the High-resolution Image Reconstruction Techniques becomes realistic. The aim of this paper is to show the feasibility of such detection on the 2. 4-meter telescope, within certain range of object luminosity. This is based both on experiments and theoretical calculation.
