根据衍射理论及艾里函数的定义, 在考虑产生艾里光束立方相位掩模板的中心偏离傅里叶变换透镜光轴的情况下, 理论推导了艾里光束的强度峰值轨迹表达式, 并研究了光束初始发射角对艾里光束加速轨迹的影响。研究发现在横向加速度一定的情况下, 初始发射角越大, 光束传输轨迹的变化越大。利用全息缩微输出系统制备较大尺寸的相位掩模板, 产生了加速艾里光束, 较大幅度地改变了艾里光束的初始发射角, 并达到了大幅度调控艾里光束传输轨迹的目的。

Based on the diffraction theory and the definition of Airy function, a trajectory expression of the intensity peak of Airy beam is deduced theoretically when the central position of cubic phase mask deviates from optical axis of Fourier transform lens, and the influence of the initial launch angle on the acceleration trajectory of Airy beam is discussed. We find that when the lateral acceleration is a constant, the larger the initial launch angle is, the larger the initial launch angle changing is. In order to increase the initial launch angle, we manufacture cubic phase mask with big size using computer-generated hologram microfilming printing system. Accelerating Airy beams are generated with the phase mask, and the propagation trajectory of Airy beam can be controlled within a large range when the dislocation between the center of phase mask and optical axis of Fourier transform lens is changed.
