用菲涅耳近似研究了标量光场的衍射和自由传播。从傍轴波的微分方程出发，统一地推导了它的性质。利用分离变量法，可以直接得到伪平面波、伪球面波和高斯光束等有意义的场分布。以下主题也被处理：菲涅耳衍射积分，逆传播，菲涅耳变换，一些不变的亲和变换的性质，和公式允许评估，在每一个点的领域，分布的错误连接到菲涅耳近似。
Examines the diffraction and the free propagation of an optical scalar field by means of the Fresnel approximation. In a unified way, deduces its properties from the differential equation of paraxial waves. By means of the variable separation method, one can obtain directly significant field distributions like: pseudoplane waves, pseudospherical waves and Gaussian beams. The following topics are also treated: the Fresnel diffraction integral, inverse propagation, the Fresnel transformations, some invariant properties for affinity transformations, and formulas which permit an evaluation, in every point of the field, of the distribution of the error connected to the Fresnel approximation.
