AI 中文摘要
对直接发现和表征类地系外行星的追求，推动了使用具有窄内工作角日冕仪的高对比度成像巡天。然而，传统成像方法受限于轴上点扩散函数（PSF）的尺寸，通常仅能探测角分离度大于2λ/D的伴星。与此同时，非冗余掩蔽（NRM）技术已被用于单孔径望远镜，以在衍射极限内的角尺度上干涉分辨天体物理特征，但NRM干涉测量对高对比度天体存在灵敏度问题。在本研究中，我们探究将高对比度日冕仪与NRM干涉测量结合使用，对这种组合架构进行初步研究，旨在确定传统高对比度成像内工作角内高对比度目标的性能和发现空间的潜在边界。我们预测，将这些技术结合可提升光子限观测的可实现对比度，同时还估算了该系统的波前稳定性要求。
英文摘要
The pursuit of the direct discovery and characterization of Earth-like exoplanets has motivated high contrast imaging surveys using coronagraphs with narrow inner working angles. Traditional imaging methods, however, are limited by the size of the on-axis PSF and typically only detect companions at angular separations of > 2$λ$/D. Meanwhile, non-redundant masking (NRM) techniques have been used with single-aperture telescopes to interferometrically resolve astrophysical features at angular scales within the diffraction limit, but NRM interferometry faces sensitivity issues for high-contrast objects. In this project, we investigate utilizing high contrast coronagraphy in conjunction with NRM interferometry. We conduct a preliminary investigation of this combined architecture with the goal of determining the potential bounds of performance and discovery space for high-contrast targets within the inner working angle of traditional high-contrast imaging. We predict an improvement in the achievable contrast for photon-limited observations by combining the techniques, and we also develop estimates for wavefront stability requirements for the system.
