摘要
提出了一种利用计算机产生和再现具有缺陷结构和复式结构的二维光子晶体的菲涅尔全息图的数字方法。采用博奇编码方法,应用C语言和Matlab语言的混合编程下实现全息图的制作,并直接应用数字滤波技术消除了虚象和零级象,模拟再现出实象。
A numerical method of was presented, which was for fabricating and reconstructing Fresnel hologram of defect or compound structure 2D photonic crystal. The hologram was generated through Burch coding method fulfill with C and Matlab. By using digital filter method, twin- images and zero-order diffract ion images are eliminated and real-images are obtained.
