摘　　要：采用多层相位屏法和分步傅里叶算法相结合的方式来模拟环形艾里光束在湍流大气中传输时光斑质心漂移。通过理论和实验仿真了环形艾里光束在湍流中的传输。通过比较,证实了环形艾里光束在湍流中传输时扰动漂移量小于艾里光束和高斯光束。因此,利用环形艾里光束作为信息载体在远距离传输时具有很大的应用潜力。The method of combined multiple phase screens and split-step Fourier to simulate the drift behavior of circular-Airy beams in atomspheric turbulence is proposed. The propagation of circular-Airy beams in turbulence is simulated theoretically and experimentally. Through comparing the drift behavior of Airy beams with related Gaussian beam, it is found that the drift distances of circular-Airy beams are less than that of reference beams.Therefore, employing the circular-Airy beams as information carrier has potential application for long-distance transmission.
