摘要
During the 2008 total solar eclipse, the coronal emission lines were observed by using optical fibre spectrometric and polarization imaging system in near infrared waveband. The profiles of the coronal emission lines including Fe XIII 10747 angstrom, 10798 angstrom and He I 10830 angstrom were obtained with dispersion of 0.5 angstrom/pix. The intensity of Fe XIII 10747 angstrom remained unchanged in the two different coronal regions while the intensity of He I 10830 A varied considerably in the two coronal locations no matter whether the prominence appeared or not. The coronal polarization images were observed at Fe XI 7892 angstrom with a bandpass of 30 angstrom in a series of exposure times.
