根据谱线轮廓对恒星进行表面成像已成为现代天体物理学的重要工具。它目前用于绘制Ap星上化学元素的分布以及晚型星表面温度的变化。一旦获得高质量的偏振观测结果，就会生成磁场图。最近，成像技术已被开发用于食双星。在本文中，我们回顾了我们发现的改进，这些改进可以在表面成像的各个方面产生更可靠和更详细的地图。
Surface imaging of stars from the profiles of spectral lines, has become an important tool in modern astrophysics. It is presently used for mapping the distribution of chemical elements on Ap stars and the variation in temperature over the surface of late-type stars. Magnetic field maps will be produced as soon as high quality polarization observations are available. Recently imaging techniques have been developed for application to eclipsing binary stars. In this paper we review the improvements we have found to result in more reliable and detailed maps in all aspects of surface imaging.
