论文摘要
我们报告了2017年8月21日在美国爱达荷州雷克斯堡（美国）的日食总太阳日食的偏光观察结果。我们使用三个同步的DSLR摄像机，其在0°，60°和120°的极化过滤器中，提供了电晕和周围天空的高动力范围RGB极化图像。我们按预期的是，我们测量切向冠状动脉极化和垂直天空极化。这些观察结果提供了详细的检测到在绿色太阳上方和下方的极化中性点的详细检测，其中冠状极化被天空极化取消。我们将这些特殊的极化中性点命名为Minnaert和Van de Hulst。
We report the results of polarimetric observations of the total solar eclipse of 21 August 2017 from Rexburg, Idaho (USA). We use three synchronized DSLR cameras with polarization filters oriented at 0°, 60°, and 120° to provide high-dynamic-range RGB polarization images of the corona and surrounding sky. We measure tangential coronal polarization and vertical sky polarization, both as expected. These observations provide detailed detections of polarization neutral points above and below the eclipsed Sun where the coronal polarization is canceled by the sky polarization. We name these special polarization neutral points after Minnaert and Van de Hulst.
