In this paper, we present the feasibility of compensation of color breaking in a holographic-optical-element based augmented reality (AR) display. We first build up a theoretic optical model of the AR display system to evaluate the color breaking of displayed white image from the user’s point of view. During the calculation, the color coordinate of each pixel of projected virtual image can be obtained. Therefore, based on those calculated results, we propose a color correction algorithm by applying a pre-compensation scheme to the R/G/B values of each display pixel. This method enables the full-color image in AR system applications.

Vision Correction via Electrically Tunable Liquid Crystal Lens for Near-Eye Display System
Wei-Cheng Cheng, Yi-Hsin Lin, Yu-Jen Wang, National Yang Ming Chiao Tung University (Taiwan); Victor Reshetnyak, Taras Shevchenko National University (Ukraine); Chuan-Chung Chang, Fu-Ming Chuang, Coretronic Corporation (Taiwan)
The vision correction for near-eye display by using an electrically tunable lens based on the spatially extended LC lens is demonstrated in this paper. For the first time, we found that the spatially extended LC lens shows the spatially distribution in lens power ranging from +3.25D to -3.25D. The surprising results give LC lenses an insightful aspect and overrule the traditional statement of the limitation of lens power set by the optical phase difference in gradient-index LC lenses. It also paves a way in ophthalmic applications.

Xiao-Ching Lin, National Changhua University of Education (Taiwan); Wen-Kai Lin, Shao-Kui Zhou, National Yang Ming Chiao Tung University (Taiwan), National Changhua University of Education (Taiwan); Wei-Chia Su, National Changhua University of Education (Taiwan)
In this study, the proposed near-eye display (NED) system is composed of two holographic waveguides with wavelength multiplexing. Each holographic waveguide is designed to offer half FOV for the whole system. After combination of these two waveguides, rhe NED system FOV can reach 50°×20.71° (H×V).

Electrically tunable focusing liquid crystal lenses based on multiple-zone and three-dimensional curved electrodes
Yu-Ci Huang, Ching-An Chih, National Central University (Taiwan); Shao-Che Sun, National Taiwan University (Taiwan); Cheng-Kai Liu, National Central University (Taiwan); Guo-Dung Su, National Taiwan University (Taiwan); Ko-Ting Cheng, National Central University (Taiwan)
In this study, the research topic is the electrically tunable focusing large aperture liquid crystal lens with three-zone and three-dimensional curved electrodes. The three-dimensional curved electrodes are designed by separating the ideal phase profile into three zones according to the structures of Fresnel lenses, and the optical path difference between any two adjacent zones of the three-dimensional electrode is an integer multiple of 2π. The performances of the LC lens, such as the electrically tunable focus, response time, and others, are also discussed.

Image-based polarization detection and material recognition
HAO-HSIN HUANG, WEI-HSIANG JEN, YU-JEN WANG, HUAI-AN HSIEH, YI-HSIN LIN, National Yang Ming Chiao Tung University (Taiwan); PO-LUN CHEN, General Interface Solution Holding Ltd. (Taiwan)
We demonstrate a single-shot and image-based polarization detection system for material recognition. The stokes parameters are measured under a single-shot measurement using 4 electrically tunable liquid crystal wave plates, 4 polarizers and 4 camera modules. The optical principle is introduced and the experiments are performed. We also use a metallic plate and a glass substrate to demonstrate the material recognition. The impact of this study is to provide a practical way in image-based polarization detection in Advanced Driver Assistance Systems for material recognition which could help in driving safety.

optimizing the thermal annealing duration of emitting layer, the maximum current efficiency of 0.83 cd/A, emission
peak wavelength of 590 nm and CIE coordinates of (0.49, 0.45) can be achieved.

Implementation of meta-gratings for augmented reality (AR) glasses using double patterning with KrF photolithography
Chun-Yen Chou, Peichen Yu, Yu-Teng Chen, National Yang Ming Chiao Tung University (Taiwan)
In our research, we design three gratings to realize the AR glasses at wavelength 520nm. Besides that, we optimize the structure of grating to obtain uniform output efficiency. However, slant grating is difficult to fabricate through photolithography. To solve this problem, metagrating is a way to deal with it. By using double patterning technique, we succesfully build a metagrating which critical dimension reaches 50nm via KrF scanner.
