提出了一种基于偏振干涉的消色差恒星日冕仪。介绍了零星日冕仪的工作原理和光学装置。单色光和白色光的实验结果表明了该方法的有效性。采用液晶器件作为四象限偏振掩模，该掩模是偏振干涉式恒星日冕仪的关键元件。
A nulling stellar coronagraph based on polarization interferometry is proposed that has achromatic characteristics. The principle and the optical setup of the nulling stellar coronagraph are described. Experimental results with monochromatic and white light show the usefulness of the proposed method. A liquid-crystal device is used as a four-quadrant polarization mask, which is the key element of a polarization interferometric stellar coronagraph.
