Cheng-Te Peng Holographic approach for light bending and guiding in a volume hologram
Cheng-Te Peng,

A concept of 90 degree light bending by holography for solar concentrator is presented. For achieving higher diffraction efficiency, the optical properties of the phenanthrenequinone-doped poly(methyl methacrylate) photopolymer (PQ/PMMA) are present and discuss. The optical experimental results demonstrate that the diffracted beam can bending 90 degree with respect to the input beam.

Chun Ting Lin Stacked volume holograms for spectrum-division
ChunTing Lin,AnChi Wei,JingHeng Chen,JuYi Lee,PeiFang Hung,ChiaMing Li,HongCheng Huang,HongYih Yeh,

A spectrum-division technique using stacked volume holograms is proposed for high angular tolerance. . According to the coupled-wave theory, the diffraction efficiency of such a stacked system is derived. The simulated results show that an angular tolerance of -7° ~ +4° has been achieved with the maximal diffraction efficiency of 95%.

Chih-Yuan Cheng Improvement the Performance of the Collinear Holographic Data Storage System
Chih-Yuan Cheng,Yeh-Wei Yu,Ching-Cherng Sun,

In this paper, we describe two techniques to improve the performance in the collinear holographic data storage system. The piston light value technique is added in the storage system, so that the phase information is converted into the intensity information, and the traditional binary encoding could be converted into the three-level encoding technique. The homodyne detection technique is added in the storage system, so that the multiplying relationship between the intensity of the diffraction pattern and noise is converted into the adding relationship. Therefore, the quality of the diffraction pattern could be enhanced.

Wei Wang Iris Texture Recovery by Independent Component Analysis and Multi-Spectral Imaging
Wei Wang,Sheng-Hsun Hsieh,Chong-Hao Tien,

Iris recognition has proven its accuracy and gained importance in biometric recognition. However, the presence of contact lens, particularly the cosmetic lens, has been proved to deteriorate the iris pattern and the accuracy of recognition. In this study, we propose a blind source separation method by multi-spectral imaging to separate the pattern of iris and cosmetic lens.

Hao-Chien Chiu Study and Simulation of Optical Coherence
Hao-Chien Chiu,Jie-En Li,Jhih-Syuan Fu,Chun-Hao Tien,

The optical coherence not only represents the statistical behaviors of the light but also plays an important role in the realm of phase-space optics. In this work, we present the fundamental knowledge of the coherence and simulate two kinds of mutual intensity functions to analyze this property.
