摘要

采用光场的一阶矩和二阶矩作为评价参数，研究了偏振部分相干激光波束在斜程湍流大气传输中的漂移效应和扩展效应。根据推广的惠更斯菲涅耳原理，以椭圆偏振部分相干激光波束为研究对象，推导了斜程传输情况下波束的重心坐标、扩展半径和扩展角的表达式，数值分析了偏振波束两正交分量的相位差、方向角、波长、初始束腰半径和接收机高度对波束漂移及扩展的影响。结果表明，在确定的斜程传输距离和接收机高度下，随着偏振波束两正交分量相位差的增大，漂移效应先增大后减小，在确定的斜程传输距离下，接收机高度越高,波束的漂移效应和扩展效应越小。

Abstract

Wander and spreading of polarized and partially coherent laser propagation on slant path in turbulence atmospheric are studied by using the first and second moment of optical field as evaluation parameters. According to extended Huygens-Fresnel principle, the elliptically polarized and partially coherent laser beam is taken as a study object. The analytical expressions for barycentric coordinate, spreading radius and spreading angle of beam on the slant path are derived, and the effects of the phase difference between two orthogonal components of polarization beam, direction angle, wavelength, initial waist radius and receiver height on wander and spreading of laser beam are analyzed. Results show that the wander effect increases at first, and then decreases with the phase difference between two orthogonal components of polarization beam increasing under the certain slant path transmission distance and receiver height. The effect of wander and spreading of beam decreases with the increase of receiver height under the certain slant path transmission distance.
