Wei-Yao Chang Award Candidate Development of Calibration System
Wei-Yao Chang,Yen-Chang Chu,Fan-His Hsu,Chien-Hung Yeh,Jing-Heng Chen,Jiun-You Lin,Ken Y. Hsu,Kun-Huang Chen,

This paper develops a calibration system. Because the collimating lens is not required to scan, this system can rapidly perform light beam collimation testing and calibration.

Chia-Hao Guo Award Candidate Optical Scanning Holography in the Coherent Mode
Chia-Hao Guo,Jung-Ping Liu,

It is difficult to implement optical scanning holography in the coherent mode for the scattered object because the light scattered from the object is extremely weak. In the paper we successfully acquired such coherent-mode scanning holograms.

Kai-Chung Teng Award Candidate Speckle Suppression in Spatial Phase-Shift Patterns Using An LCoS Spatial Light Modulator
Kai-Chung Teng,Ming-Hong Weng,Jun Hao Lee,Wei-Feng Hsu,

We presented a method to improve the image quality of the diffractive phase-shift patterns (PSPs) which were generated by diffractive optical elements implemented by a spatial light modulator. By temporally integrating a sequence of diffraction patterns degraded with speckles, the speckles were suppressed and the destructive line became clearly observed.

Chin-Yu Liu Award Candidate Resolution enhancement of synthetic aperture digital holography based on spectrum normalization
Chin-Yu Liu,Wei-Jen Hsiao,Xin-Ji Lai,Han-Yen Tu,Yu-Chih Lin,Chau-Jern Cheng,

This work demonstrates a resolution enhancement method for synthetic aperture digital holography based on spectrum normalization technique. Experimental results indicate that the spatial resolution and signal-to-noise ratio of the synthesized reconstructed image are improved simultaneously under low numbers of the acquired holograms.

Ching-Hwa Ho Award Candidate Growth, Structural and Optical Properties of a- and r-Phase In2Se3 Layered Crystals
Ching-Hwa Ho,

In2Se3 crystals show black shiny for a-phase and red to yellow for the r-phase. The a-In2Se3 achieves wide-energy-range photoelectric conversion owing to the existence of surface oxide (oxygen detection). The a←→r inter-phase transition promote feasible applications of r-In2Se3 suitable for optical-memorial sensing and memory devices.

Po-Kai Hsieh Award Candidate Design Scheme of Programmable Fresnel Lenslet Array for Projecting 2D/3D Images Using An LCoS Spatial Light Modulator
Po-Kai Hsieh,Tai-Yuan Chen,Yi-Hsuang Weng,Wei-Feng Hsu,

We present a method to design programmable Fresnel lenslet array (PFLA) which is used as the input to an liquid-crystal-on-silicon spatial light modulator (LCoS-SLM) for projecting 2D/3D light-spot images. The system can be adopted for the applications such as 3D imaging and head-up displays.

Cheng Hung Chi,Shiuan Huei Lin,

We present a method to create a Kinoform CGH which is made from the 3D computer graphic models composed of 2D polygons. The analytical approach is used to avoid complicated FFT computation for reducing time consuming. In addition, the optical reconstruction of the synthesized CGH is demonstrated.

Fan-Hsi Hsu Award Candidate Prism-hologram-prism Sandwich Recording Method for Polarization-selective Substrate-mode Holograms
Fan-Hsi Hsu,Jing-Heng Chen,Kun-Huang Chen,Ken-Yuh Hsu,

In this paper, we proposed a novel recording method of polarization-selective volume holograms with a large diffraction angle. The hologram is sandwiched between two 45°-90°-45° prisms and can easily record the interference fringes in the recording material with only one beam.

Ching-Hsiang Kang Award Candidate High Dynamic Range Imaging Applied in Extended Depth of Field Technology
Ching-Hsiang Kang,Sheng-Hsun Hsieh,Chung-Hao Tien,

Extended depth of field (EDoF) can expand the acquisition volume of an image system. However, the performance of EDoF was constrained by the imperfect of the input image. In this study, we proposed an algorithm to lower the flaws caused during the EDoF acquisition process by computational scheme.

TSAI YI TING Pattern Recognition based on HSL Color Model by the Multi-Channel Liquid Crystal Optoelectronic Correlator with Shift and Rotation Images.

This research uses the minimum average correlation energy method and shifted training images to recognize the polychromatic images based on Mach-Zehnder joint transform correlator. It leads to that the correlation output peak is much sharper and the input is proper to the liquid crystal device of input plane. In our former research, the training images are displayed at the center position. However, the total sidelobe energy may not be the minimum. In order to solve the problem, we transform the color image into three HSL color space components. Then, three components are rotated from 0° to 360° in steps of 5° and shifted from -5 to 5 pixels in both of vertical and the horizontal directions to yield training images. The system can deal with rotated images.
