【摘要】 基于非稳光场的相干光理论,研究了部分空间和部分光谱相干高斯-谢尔模型脉冲光束在大气湍流中的光谱变化规律。给出了部分空间和部分光谱相干高斯-谢尔模型脉冲光束在大气湍流中的光谱传输公式。通过数值计算,详细分析了大气湍流的折射率结构常数、光阑截断参数、脉冲时间相干长度,空间相干参数对脉冲光谱位移和光谱开关的影响,并对所得主要结果作了物理解释。更多还原

【Abstract】 Based on the non-stationary light wave fields theory,the spectral changes of diffracted spatially and spectrally partially coherent Gaussian-Schell model pulsed beams through atmospheric turbulence are studied analytically and numerically.An analytical expression for the diffracted spatially and spectrally partially coherent Gaussian-Schell model pulsed beams through atmospheric turbulence is derived.And numerically analyzed influence of the refractive index constant,truncation parameter,temporal coherence length and spatial coherence parameter on spectral shifts and spectral switches.The main results are interpreted physically更多还原
