利用广义惠更斯-菲涅耳衍射积分公式得到了带球差的部分相干光束在海洋湍流中传输的光强表达式,通过数值计算研究了带球差的部分相干光束在海洋湍流中传输的光强特性。研究表明:均方温度耗散率χT较大、单位质量液体中的湍流动能的耗散率ε较小或者温度和盐度波动的相对强度w较大时,海洋湍流对光束的扩展影响较大;χT较小、ε较大或者w较小时,海洋湍流对光束的扩展影响较小;光束的相干长度越小,或者球差越大,光束越扩散。光束在海洋中传输时,球差参数对光束扩散的影响明显小于海洋参数对光束扩散的影响。 Using the generalized Huygens-Fresnel diffraction integral formula, the light intensity expression of the partially coherent beam with spherical aberration propagating in ocean turbulence is obtained. The numerical results show that the partially coherent beam with spherical aberration propagates in ocean turbulence Light intensity characteristics. The results show that when the mean square temperature dissipation rate χT is large, the turbulent kinetic energy dissipation rate ε per unit mass of liquid is small, or the relative intensity w of temperature and salinity fluctuation is larger, the ocean turbulence has a greater influence on the beam expansion ; when χT is smaller, ε is larger or w is smaller, ocean turbulence has less effect on the expansion of the beam; the coherence length of the beam is smaller, or the larger the spherical aberration, the more diffused the beam. When the beam is transmitted in the ocean, the influence of the spherical aberration parameter on the beam diffusion is obviously smaller than the influence of the ocean parameter on the beam diffusion.
