摘要: 基于拓展的惠更斯-菲涅尔原理,推导出了圆对称阵列光束在各项异性湍流大气中传输的束腰宽度和光束漂移解析表达式,并对此表达式进行了数值模拟。结果表明:圆对称阵列光束在各项异性湍流大气传输时,阵列光束的高斯光束个数对光束漂移的影响较小,而高斯阵列所围成圆环的半径对光束漂移的影响较大,半径越大,阵列光束的漂移越小;各项异性湍流大气的幂律参数和各项异性因子也是影响光束漂移的主要因素。在相同条件下,阵列光束受到各项异性湍流大气的扰动比高斯光束小。

Abstract: Based on the extended Huygens-Fresnel principle, the analytical expressions of the beam width and beam wander for radial array beams in anisotropic turbulent atmosphere are derived. The numerical analysis results show that the beam wander of radial array beams is influenced by the number of Gaussian beam small, but the radius of the ring is large. There is small beam wander for radial array beams with the large radius of the ring. Beam wander is also mainly affected by the power law and anisotropic factor in anisotropic turbulence. At the same conditions, laser array beams in anisotropic turbulent atmosphere are less disturbed than Gaussian beam.
