AI 中文摘要
本研究旨在提出一种基于遥远光源场的维格纳函数相关性的干涉测量新方法，对维格纳函数的相关性展开理论研究，数值模拟验证了相关结论。结果表明，与场的相关性相比，维格纳函数的相关性可采样光源强度分布两倍的空间频率，空间图案尺度约小一半，这为将干涉测量的角分辨率提升一倍提供了基础可能性。
英文摘要
Aims. This work aims to introduce a new method of interferometric measurements based on correlation of Wigner functions constructed for the fields from a distant source. Methods. This work presents theoretical studies of correlation of the Wigner functions. Numerical simulations support the findings. Results. It is shown that in comparison to the correlation of the fields, a correlation of their Wigner functions samples twice higher spatial frequencies of the source intensity distribution and has about twice smaller scale of the spatial pattern. This opens a fundamental possibility to improve the angular resolution of interferometric measurements by a factor of two.
