摘要
通过将矩孔函数展为有限个复高斯函数之和的方法,对直角坐标系中的平顶高斯光束在有光阑限制ABCD光学系统中的传输作了研究,得到了近似的解析传输公式,并用数值计算例证明了它们的正确性.
Abstract
By expanding the rect function into a finite sum of complex Gaussian functions, the propagation of flattened Gaussian beams through an apertured optical ABCD system is studied in the rectangular coordinate system, and approximate analytical propagation formulas of flattened Gaussian beams are derived. The validity of our formulas is illustrated with numerical examples.
