Challenges of Near to Eye Display for Augmented Reality
Fu-Ming Chuang;Hsin-Hsiang Lo;Chuan-Chung Chang;Chung-Jen Ou

Augmented Reality (AR) displays are attracting significant attention and efforts recently. One of the solution to compromise both the time multiplexing and Vergence-Accommodation Conflict (VAC) is the Varifocal lens (VFL) based approach. This report addressed four major challenges on VFL-AR system, and the results suggest feasible treatments for better user experiences.

Fast Frequency-resolved Optical Gating Convergence based on Time and frequency Constrains
Jui-Chi Chang;Chia-Yuan Chang

The frequency-resolved optical gating (FROG) is powerful technique for measuring the ultrashort laser. However, the reconstruction algorithm based on iterative process lowers the detection rate. In this paper, utilizing the time and frequency constrains, we can estimate the initial electrical function of amplitude and phase to improve the convergence rate.

Asymmetric Light-guide Design for LED Headlight with Nonuniformity Light Pattern
Cheng-Ching Chen;Jia-bao Shen;Tsung-Xian Lee

The purpose of this paper is to focus on the design of the optical module of LED projection headlight with an asymmetric light-guide and remove the shield. We propose three structures and optimize them, including coaxial, curved and combined light-guide.

Single Reflector for High-intense High/low Beam for ECE Regulation
Shih-Kang Lin;Yu-Hsiang Lee;Chih-Shou Wu;Yeh-Wei Yu;Tsung-Hsun Yang;Ching-Cherng Sun

In this paper, we proposed an optical design for both high beam and low beam in a single reflector. The performance of the final design has been proven both meeting the regulation in simulation and experiment. The maximum illuminance reaches to 396 lux in simulation and 226.8 lux in measurement.

The Study of Array Illumination Module for Adaptive Headlight System Application.
Kao-Der Chang;Jui-Wen Pan;Luan-Ying Chen

Adaptive headlight system is an optical control technology that can adjust the light distribution of headlight depending on the driving environment. This system utilizes multiple collimated light to assemble automotive lighting areas with pixels. The distribution of the headlight can be changed when controlling the greyscale of the pixel.
