摘要
在Rvtov近似和采用Tatarskii湍流大气折射率起伏谱条件下,运用实数和复数矩阵元的ABCD矩阵研究了湍流大气中广义Helmholtz-Gauss束的传输规律,研究表明广义Hellmholtz-Gauss束的横向波数与高斯束传输参量q的积在弱湍流大气传输过程中保持不变。导出了湍流大气中传输广义Helmholtz-Gauss束的平均光强。
Using the Rytov approximation and the Tatarskii spectrum of refractive index fluctuations of turbulent atmosphere, we analyze the propagation of Generalized Helmholtz- Gauss beam（gHzG） in turbulent atmosphere by ABCD matrices with real and complex elements. The results show that the product of the transverse wavenumher and the parameter q remains constant under propagation in weak atmospheric turbulence. A closed - form expression for the intensity of gHzG beams is derived.
