文章介绍了怀柔太阳观测基地最近完成的一套实时高分辨太阳磁场观测系统.系统采用局部相关跟踪算法来提高磁场观测数据的空间分辨率,同时对相关跟踪算法的实现程序进行了优化以满足常规太阳磁场观测的要求.通过对试观测和常规观测数据的分析,我们发现:1)该系统能够大大提高单色像、磁场数据的对比度和空间分辨率;2)对相关跟踪算法的优化大大提高了系统的时间分辨率,系统可以投入常规观测使用.

In this paper,we introduce a recently finished imageprocessing system for the highresolution observation of solar magnetic field in the Huairou Solar Observing Station (HSOS).The Correlation Tracking (CT) method is used in this system to improve the spatial resolution, and the algorithm of CT is optimized to improve the temporal resolution for the purpose of routine observation of solar magnetic field.We carried out some test and routine observations, and by the data analyses we conclude:1) This system can improve the contrast and spatial resolution of the filtergram and magnetogram obviously;2) The optimization of the algorithm largely improve the temporal resolution, and this makes the routine observation possible.
