Correlations of broadband speckle have important implications for passive, non-line-of-sight imaging. We examine the spectral and spatial correlations of broadband, around-the-corner speckle and reveal a set of equations that locate the spatial maximum of the paraxial spatial-spectral correlation function. We confirm the validity of the spatial-spectral correlation framework through experiment, theory and simulation.
宽带散斑的相关性对被动式非视距成像具有重要意义。我们研究了宽带拐角处散斑的光谱和空间相关性，并揭示了一组用于定位傍轴空间光谱相关函数空间最大值的方程。我们通过实验、理论和模拟证实了空间光谱相关框架的有效性。
