我们最近引入了一种受射电天文学启发的新型干涉测量方法，利用具有自校准功能的非冗余孔径（NRA）掩模，从单次干涉图中全面表征电子束的二维横向形状。本文报告了该技术的最新进展，包括基于闭合振幅的新数据分析方法，无需自校准。还展示了该方法在波前传感中的适用性，并探讨了其分辨叠加在明确高斯束芯上的束晕的潜力。
英文摘要
We recently introduced a novel interferometric method inspired by radio astronomy, utilizing a Non-Redundant Aperture (NRA) mask with self-calibration to fully characterize the two-dimensional transverse shape of electron beams from a single-shot interferogram. This paper reports the latest advancements in this technique, including a new data analysis approach based on closure amplitudes, which removes the need for self-calibration. We also demonstrate the method's applicability to wavefront sensing, and we explore its potential for resolving beam halos superimposed on well-defined Gaussian beam core.
