摘要: 使用广义惠更斯—菲涅尔衍射积分，增广矩阵和Wigner分布函数方法，研究了偏心厄米--高斯光束通过失调非对称一阶光学系统的传输特性，证明了偏心厄米--高斯光束通过一阶光学系统时保持其封闭性,光束的二阶矩矩阵按通常的规律变换，一阶矩矩阵遵循几何光线的变换规律，光束传输因子保持不变。

Abstract: Propagation properties of decentered Hermite-Gaussian beams through misaligned first-order optical systems are studied by using the generalized Huygens-Fresnel diffraction integral, augmented matrix and Wigner distribution function methods. It is shown that, as a decentered Hermite-Gaussian beam passes through the misaligned first-order optical system, the closed property is preserved, the second-order moments matrix varies with the usual law, the beam propagation factor remains unchanged, the first order moments matrix evolves, as if it were a ray of geometrical optics. -
