A flexible pseudo-mode sampling superposition method for synthesizing partially coherent sources has been introduced that can be thought of as an approximate discrete representation of Gori’s nonnegative definiteness criterion for designing spatial correlation functions. Importantly, without performing formidable mode analysis, this method enables us to develop a convenient and efficient experimental technology to customize partially coherent sources without sacrificing theoretical accuracy. As an example, we experimentally generate a new, to the best of our knowledge, class of nontrivial pseudo-Schell model sources recently proposed by de Sande et al. Our approach opens up a useful avenue for manipulating nontrivial partially coherent beams and promotes applications for optical tweezers and photolithography.

部分相干源的实验合成

已经介绍了一种用于合成部分相干源的灵活的伪模式采样叠加方法，可以将其视为设计空间相关函数的Gori非负定性准则的近似离散表示。重要的是，无需执行强大的模式分析，该方法就能使我们开发一种方便高效的实验技术，以自定义部分相干的信号源，而不会牺牲理论精度。举例来说，据我们所知，我们实验性地生成了de Sande等人最近提出的一类非平凡的伪Schell模型源。我们的方法为操纵非平凡的部分相干光束开辟了一条有用的途径，并促进了光镊和光刻的应用。
