通过在距离小面透镜不同距离处拍摄衍射图案来研究飞小面透镜的衍射，其光焦度估计为 2.03 × 104D。我们研究了三种不同的孔径直径，其菲涅耳数为单位量级。在较低的菲涅尔数处，较大的焦移是显着的。测量的衍射图案与使用基尔霍夫衍射理论计算的低菲涅尔数无像差透镜的衍射图案相对应。
Diffraction by fly facet lenses has been investigated by photographing the diffraction patterns at various distances from a facet lens whose power was estimated to be 2.03 × 104D. We studied three different aperture diameters with Fresnel numbers of the order of unity. A large focal shift was prominent at the lower Fresnel number. The measured diffraction patterns correspond to those calculated with the Kirchhoff diffraction theory for an aberration-free lens with low Fresnel numbers.
