We introduced a new class of a partially coherent source that can generate a field with a hollow rectangular profile, named the hollow rectangular multi-Gaussian Schell-mode source. The dependence of distribution of far-zone spectral density on the properties of the proposed source was analyzed. The results show that one can control the distribution properties of the far-zone intensity profile, including the thickness of the hollow edge, the shape of the hollow, the size of the hollow, and the orientation of the hollow, by adjusting the corresponding structural parameters of the source.

空心矩形多高斯Schell模型源。

我们引入了一种新的部分相干源，该源可以生成具有空心矩形轮廓的场，称为空心矩形多高斯谢尔模式源。分析了远区光谱密度分布对拟议源特性的依赖性。结果表明，通过调整相应的结构，可以控制远区强度分布的分布特性，包括空心边缘的厚度，空心的形状，空心的大小和空心的方向。源的参数。
