摘　　要：利用高斯-谢尔模型的交叉谱密度公式和惠更斯衍射积分,得到了部分相干Airy光束的表达式.对不同相干度的部分相干Airy光束的无衍射和横向加速偏移的性质进行了理论分析并予以实验验证,结果一致表明部分相干Airy光束也具有无衍射和横向加速度的特性,而且相干度越低,部分相干Airy光束的无衍射距离越短,横向加速度越小.Based on the cross-spectral density function of Gaussian Shell-Model and Huygens integral, the expression of partially coherent Airy beam was derived. The non-diffraction and acceleration characteristics of partially coherent Airy beam were theoretically studied and experimentally observed. The experimental observation was consistent with the theoretical prediction. Furthermore, the non- diffraction distance and the transversal acceleration decrease with decreasing coherent length.
