NST近红外成像光谱仪仪器串扰的校正

Calibration of the Instrumental Crosstalk for the Near-IR Imaging Spectropolarimeter at the NST

Kwangsu Ahn, Wenda Cao

摘要:

近红外成像分光偏振仪(NIRIS)是安装在大熊太阳天文台新太阳望远镜上的偏振仪。该仪器具有最高的空间分辨率和通量。主镜是同轴型的,因此我们感兴趣的是评估其对斯托克斯参数之间的串扰的贡献,因为我们不能将我们的校准光学器件放在镜之前。我们想提出我们的努力,以补偿斯托克斯轮廓之间的串扰所造成的中继光学从望远镜到检测器。并介绍了整个数据处理流水线。

英文摘要:

The Near-IR Imaging Spectropolarimeter (NIRIS) is a polarimeter that is installed at the New Solar Telescope at Big Bear Solar Observatory. This instrument takes advantages of the highest spatial resolution and flux. The primary mirror is an on-axis type, so it was our interest to evaluate its contribution to the crosstalk among the Stokes parameters since we could not put our calibration optics before the mirror. We would like to present our efforts to compensate for the crosstalk among Stokes profiles caused by the relay optics from the telescope to the detector. The overall data processing pipeline is also introduced.
