相比单束光，阵列光束由于各光束之间互不相干，可以减小大气湍流引起的接收光强起伏。特别在激光照明和通信等应用场合中，非相干合成光束可以明显提高照明均匀性和减小通信误码率。简要介绍了相干合成阵列光束在湍流大气中传输的光强闪烁研究进展。针对非相干合成阵列光束在减小光强闪烁的优势，回顾了非相干合成阵列光束在激光主动照明、星地激光大气通信方面的实验研究结果；详细总结了子光束为不同类型的非相干合成阵列光束的理论研究方法和结果，包括不同波长光、基模高斯光、部分相干高斯光和艾里光。实际中子光束一般为部分相干光，它们互相之间存在相干性。提出了下一步应深入开展研究的问题为阵列光束大气的光强闪烁。

Compared with single beam, arrays beams which are composed of spatially separated beamlets are suggested to be used for scintillation reduction. Incoherent combined array laser can distinctly reduce intensity fluctuations and signal fades in active illumination and optical communications. Research progress of scintillations for kinds of laser array beams in atmospheric turbulence is depicted, including coherent and Incoherent combined array laser. In view of the advantage of incoherent combined array laser, the experiments of laser illumination and satellite laser communication have been summarized simply. And the means and results of kinds of beam arrays are described, including different wavelengths beam, fundamental Gaussian beam, partially coherent Gaussian beam and Airy beam. Problems that should be further studied are presented.
