摘要
大气对激光传输的影响因素很复杂,如大气湍流、大气气溶胶及大气分子(如CO2、H2O和O3)的吸收和散射等。气溶胶和大气分子的吸收和散射引起激光能量的衰减,作用距离下降;大气湍流引起激光束的偏转、抖动,强度起伏(闪烁)等效应,使激光的空间相关性下降,影响激光的作用效果和精度。详细论述了这些因素对激光大气传输的影响。
The factors are complex when laser transmission in the atmosphere such as atmospheric turbulence, atmospheric aerosols and atmospheric elements (such as CO2、H2O and O3), such as the scattering and absorption. Aerosols and atmospheric absorption and scattering of laser energy from the decay, from the role of decline in atmospheric turbulence caused the laser beam deflection, jitter, intensity fluctuations (blinking) and other effects, so that the laser’s space-related decline, the impact of the effects of la...
