摘要

本文给出了有限空间平面周期光栅衍射场的解析表达式。首先假定照明是完全相干的。利用新的“傅立叶伪系数”分析了物体有限尺寸对菲涅耳模式的影响。我们还分析了部分相干照明的情况。

Fresnel patterns of finite grating illuminated by coherent and partially coherent fields

We give, in this paper, the analytical expression for the field diffracted by a spatialy limited plane periodic grating. The illumination is first assumed to be completely coherent. The influence of the finite size of the objet on the Fresnel patterns is analysed by means of new « Fourier pseudo-coefficients ». We also analyse the partially coherent illumination case.
