论文摘要
我们提出了一种通过直接测量场强度和其空间波动的离线分析来查找热场的2D空间模式的方法。使用此方法，我们以一种简单有效的方式重建了多模纤维的模式以及通过高增益参数下调转换产生的挤压真空的空间Schmidt模式。重建的形状与理论结果一致。
We propose a method for finding 2D spatial modes of thermal field through a direct measurement of the field intensity and an offline analysis of its spatial fluctuations. Using this method, in a simple and efficient way we reconstruct the modes of a multimode fiber and the spatial Schmidt modes of squeezed vacuum generated via high-gain parametric down conversion. The reconstructed shapes agree with the theoretical results.
