Nano-kirigami enables direct and versatile shape transformations from two-dimensional predesigns to three-dimensional (3D) architectures in microscale/nanoscale. Here a new and extensible strategy for cascaded multilayer nano-kirigami is de......
Three-dimensional image authentication using binarized images in double random phase integral imagin
[期刊论文] 作者：WeitaoSong,QijiaCheng,YueLiu,YuanjinZheng,ZhipingLin,YongtianWang,
来源：ChineseOpticsLetters 年份：2019
We proposed a three-dimensional (3D) image authentication method using binarized phase images in double random phase integral imaging (InI). Two-dimensional (2D) element images obtained from InI are encoded using a double random phase encry......
Analysis of optical characteristics of modulation devices with square and circle pixels for 3D holog
[期刊论文] 作者：XiaoMa,JuanLiu,ZhaoZhang,XinLi,JiaJia,BinHu,YongtianWang,
来源：ChineseOpticsLetters 年份：2015
With the development of the micro/nanolithography, the optic–optic or optic–electronic modulation devices with different pixel shapes and sizes can be used for three-dimensional (3D) dynamical holographic display. The influence of differe......

Ultrathin flat metalenses have emerged as promising alternatives to conventional diffractive lenses, offering new possibilities for myriads of miniaturization and interfacial applications. Graphene-based materials can achieve both phase and......
Boundary segmentation based on modified random walks for vascular Doppler optical coherence tomograp
[期刊论文] 作者：YongHuang,ChuanchaoWu,ShaoyanXia,LuLiu,ShanlinChen,DediTong,DanniAi,JianYang,YongtianWang,
来源：ChineseOpticsLetters 年份：2019
Vascular Doppler optical coherence tomography (DOCT) images with weak boundaries are usually difficult for most algorithms to segment. We propose a modified random walk (MRW) algorithm with a novel regularization for the segmentation of DOC......
