从海洋大气相对湿度的角度建立了大气折射率变化与气溶胶激光散射特性的理论联系.在实验室条件下,分别模拟了烟、水云、尘、雾、霾等类型粒子群的蒸发波导环境,采用波长为1.06μm的激光雷达对在不同温度和湿度条件下半径范围为0.1～100μm的气溶胶粒子群进行了探测实验,并对不同气溶胶粒子群的激光后向散射回波信号特征做了对比分析,实验结果进一步验证了激光蒸发波导的可行性和有效性.
The theoretical relationship between the refractive index change of the atmosphere and the scattering characteristics of the aerosol laser was established from the perspective of the relative humidity of the marine atmosphere.Under the laboratory conditions, the evaporation duct environment of smoke, water cloud, dust, fog, haze and other particle swarms , A laser radar with a wavelength of 1.06μm was used to probe the aerosol particles with a radius of 0.1 ~ 100μm under different temperature and humidity conditions. The characteristics of laser backscattering echo signals of different aerosol particles were also studied The comparative analysis, the experimental results further verify the feasibility and effectiveness of laser evaporation waveguide.
