摘要
分析了高阶莫尔成像的放大叠合原理,并在一阶几何变换莫尔方法的基础上,通过将莫尔单元放大与周期放大过程分离,提出了一种改进的莫尔放大器设计分析方法。基于该方法,采用MATLAB对高阶莫尔成像进行模拟分析,并设计制作了多种阶次的高阶莫尔放大器,对高阶莫尔成像进行实验分析,结果体现了高阶莫尔成像的放大叠合效果,验证了所提方法的有效性。
Abstract
In this work, the amplification-superposition principle of high-order moiré imaging is analyzed. Based on the first-order geometric-transformation-moiré method, an improved design and analysis method for moiré magnifiers by distinguishing the unit amplification and periodic amplification from the moiré imaging is proposed. Our method is used to simulate high-order moiré imaging in MATLAB. By designing and fabricating various high-order moiré magnifiers, an experimental analysis of high-order moiré imaging is also carried out. The results embody the amplification-composition effect of high-order moiré imaging, thereby validating our method.
