提出了一类具有扭曲拉盖尔高斯谢尔模型（TLGSM）相关函数的部分相干椭圆源，其能够产生强度分布可能发生很大变化的光束。这种波束可以看作是LGSM波束的推广。通过与光束源和介质相关的不同量来研究自由空间和大气湍流中传播期间的谱密度特性。结果表明，椭圆形 TLGSM 波束的演化方式比 LGSM 波束复杂得多。此外，还通过定量实例进一步分析了旋转角度的行为。 (C) 2019 年美国光学学会根据 OSA 开放获取出版协议条款
A class of partially coherent elliptical sources with twisted Laguerre Gaussian Schell-model (TLGSM) correlation function is proposed, which are capable of producing beams whose intensity profiles may vary substantially. This kind of beam can be viewed as the generalization of the LGSM beams. Properties of the spectral density during propagation in free space and atmospheric turbulence are investigated with varying quantities related to the beam source and the medium. It is shown that the elliptical TLGSM beams evolve in a manner that is much more complex compared to the LGSM beams. In addition, the behaviour of the rotation angle is further analysed by quantitative examples. (C) 2019 Optical Society of America under the terms of the OSA Open Access Publishing Agreement
