摘　　要：本文用简单的算符法推导出在傍轴条件下描述光波传播过程的微分方程，然后用付氏变换求解，从中得到菲涅耳公式．We have,in this article,presented a simple operator approach to derive the partial differential equation describing the propagation of a wave envelope under the bounds of paraxial approximation. Then,the eguation can be solved by employing Fourier transform the chnigues,and the Fresnel diffraction formula is straightforwardly obtained.
