摘　　要：艾里光束具有无衍射、自加速和自愈合三大特性,其中自加速特性最吸引人。为更全面了解艾里光束的自加速特性,在保证其轨迹完整的前提下,基于几何变换改变相位图中立方相位的相对位置和旋转角度来探究艾里光束的加速特性,利用傅里叶光学推导出对应的光谱公式进行验证。结果表明,相位图几何变换调制可以显著改变艾里光束的传播轨迹位置和空间偏转位置。研究对艾里光束的自加速特性领域及应用提供了更全面的认识,对控制其他加速光束的理解提供了新的思路。Airy beams have three major properties:non-diffraction,self-acceleration,and self-healing,among which the self-acceleration property is the most attractive.To fully understand the Airy beam's self-acceleration characteristics and to ensure its trajectory's integrity,the relative position and rotation angle of the cubic phase in the phase diagram was changed based on geometric transformation to explore the transmission characteristics of the Airy beam.Fourier optics was used to derive the corresponding spectral formula.The results show that the phase map geometric transformation modulation can significantly change the position of the propagation trajectory and the spatial deflection of the Airy beam.This study provides a more comprehensive understanding of the field and application of the self-accelerating properties of Airy beams and provides new ideas for the understanding of controlling other accelerated beams.
