在本文中，我们讨论了聚焦贡献对潜在的传统菲涅耳波带片上的环的阶次的依赖性。
We investigate the dependence of the focusing contribution on the order m of local ring of underlying traditional Fresnel zone plate.
本文介绍用面积编码的方法将滤波函数为正弦函数的匹配滤波器和菲涅耳波带片组合在一起的自聚焦滤波器。
This paper presents a self focusing filter which is composed of matched filter with sine form and Fresnel zone plate by means of area coded method.
菲涅耳波带片可使入射光会聚起来，产生极大的光强，使点光源形成一系列的实像点和虚像点，其作用如同透镜成像。
Fresnel's plate can focus incident rays producing very strong brightness the function of which resembles lens forming images.
