英文摘要 | The solar chromosphere data products of the New Vacuum Solar Telescope (NVST) have been affected by the interference fringes since its first operation. These fringes have a serious impact on the quality of NVST high-resolution data, which are reconstructed by short-exposure data. In order to improve the quality of NVST high-resolution data, this article proposes a method based on "Fringes Flat Field" to remove the interference fringes in NVST short-exposure data. We made the "Fringes Flat Field" using Adaptive Wavelet Transform (AWT) and Butterworth low-pass filter. The results of the experiments are satisfactory, and the method cannot only remove the fringes effectively, but keep the solar structures from being lost. |
