为了研究相干合束激光在湍流大气中传输时，合束系统的抖动对远场的影响，采用惠更斯-菲涅耳原理推导了系统中单个光源因抖动造成偏离时的远场光强表达式。以正六边形阵列为例，分析了在不同湍流强度或者传输距离时，抖动对远场造成的的影响，并分别描绘了峰值光强及桶中功率不低于理想情况下92%时的抖动控制曲线。结果表明，抖动造成了远场的峰值光强和桶中功率的降低；当抖动范围相同时，随着湍流强度的减弱或者传输距离的减小，抖动的破坏更加严重。这一结果对研究湍流大气中的相干合束是有帮助的。

In order to study the influence of system jitter on far field of coherently combined beams propagating in turbulent atmosphere, the expression for the far field energy distribution, affected by jitter of the system, was deduced based on Huygens-Fresnel principle. Taking a hexagonal-shaped laser array as an example, the influence of jitter on far-field was also analyzed with different turbulent intensity or transmission distance.The restricted phase jitter was depicted under the condition that the maximum intensity and power in the bucket were greater than ninety-two percent of the ideal ones. It is found the maximum intensity and power in the bucket are reduced due to jitter of the system. If the scope of jitter is definite, the effect of jitter will become worse with the decrease of the turbulent intensity or transmission distance. The results are helpful to research of coherent combination propagation in turbulent atmosphere.
