摘要
斑点成象技术能有效地消除地球大气湍流的不良影响,实现地基大型天文望远镜的衍射受限分辨率成象,其所需的原始数据是天文目标及参考星的一系列的短曝光斑点象,它们取自望远镜的终端设备:斑点象探测系统。文中对比该技术对原始数据的要求:介绍了云南天文台研制的新型斑点象探测系统的结构和性能。实际观测结果表明,该系统基本能满足要求。
The serious effects of turbulence of the Earth atmosphere can be overcome so that the diffraction-limited resolution imaging of a large ground-based astronomical telescope can be achieved by the speckle imaging techniques. The original data required in these techniques are a series of the short-exposure speckle images recorded with a speckle image detection system attached to the telescope. In comparison with the requirements for the original data, structure and properties of the new speckle image detection-system built at Yunnan Observatory are introduced. Some practical observation results got with this system showed that the requirements can be basically satisfied.
