论文摘要
未来大型空间望远镜中的任何高对比度成像仪器都将包括用于测量宽带星光残留物并表征外部大气光谱的整体场光谱仪（IFS）。在本文中，我们报告了普林斯顿大学高对比度积分磁场（HCIFS）的开发，并演示了其在多光谱波前控制中的应用。此外，我们建议并实验验证了IFS成像系统的新的降低维系统识别算法，从而改善了系统的波前控制速度，对比度以及计算以及数据存储效率。
Any high-contrast imaging instrument in a future large space-based telescope will include an integral field spectrograph (IFS) for measuring broadband starlight residuals and characterizing the exoplanet's atmospheric spectrum. In this paper, we report the development of a high-contrast integral field spectrograph (HCIFS) at Princeton University and demonstrate its application in multi-spectral wavefront control. Moreover, we propose and experimentally validate a new reduced-dimensional system identification algorithm for an IFS imaging system, which improves the system's wavefront control speed, contrast and computational and data storage efficiency.
