We present the hexagonal digital moiré method for three-directional structural characterization of hexagonal packed nanostructures. A mismatch between a three-way grating and a nanoparticle assembly is shown to produce hexagonal moiré fringes due to the interference between three groups of parallel moiré patterns. The measuring principles of the pitches and the orientations of the three 1D arrays of the nanoparticles are presented. The structural information on a silica nanoparticle assembly is analyzed.
我们提出了用于六方密堆积纳米结构的三维结构表征的六方数字云纹方法。由于三组平行云纹图案的干涉,三向光栅与纳米粒子组装体之间的不匹配会产生六方云纹条纹。介绍了测量纳米粒子三个一维阵列的间距和取向的原理。分析了二氧化硅纳米粒子组装体的结构信息。
