论文摘要
斑点模式在光学方面无处不在，并且具有多个应用程序，其空间相关性至关重要。在这里，我们报告了一种通过传输矩阵的奇异值分解来设计散射介质后面的斑点相关性的方法。我们不仅表现出对斑点晶粒尺寸和形状的控制，而且还实现了具有非本地相关性的模式。此外，我们表明我们的方法的范围也沿轴向尺寸延伸，从而使体积斑点工程在散射层后面。
Speckle patterns are ubiquitous in optics and have multiple applications for which the control of their spatial correlations is essential. Here, we report on a method to engineer speckle correlations behind a scattering medium through the singular value decomposition of the transmission matrix. We not only demonstrate control over the speckle grain size and shape but also realize patterns with non-local correlations. Moreover, we show that the reach of our method extends also along the axial dimension, allowing volumetric speckle engineering behind scattering layers.
