Yu-Chien Su Liquid Crystal Devices Using Transparent Conductive Electrode of TiO2/Ag/TiO2 multilayers
Yu-Chien Su;Vera Marinova;Shiuan-Huei Lin;Ken-Yuh Hsu

The dielectric-metal-dielectric multilayer-films have received intensive attractions to develop indium-free transparent-composite-electrodes. We report the fabrication and characterization of a nematic Liquid Crystal cell with TiO2/Ag/TiO2 (TAT) multilayers, prepared by magnetron-sputtering-technique at room temperature. The electro-optical modulation characteristics and phase-retardation show great potentials of TAT thin-films for developing next-generation LC devices.

Chung Chin Chiou;Vera Marinova;Shiuan Huei Lin;Pei Chen Yu;Ken Yuh Hsu

We demonstrate the fabrication and characteristic of flexible polymer dispersed liquid crystal (PDLC) with TiO2/Ag/TiO2 layers as transparent conductive electrodes, deposited by magnetron sputtering technique on polyethylene terephthalate (PET) at room temperature is demonstrated. The transmittance dependence on the driving voltage and response time of devise are measured and discussed.

Chi-Hung Lee Long Range and High-precision Digital Spectrometer Built on a Rotary Encoder
Yi-Cheng Chen;Chi-Hung Lee;Ming-Jie Chou

In this paper, a high-precision digital spectrometer built on a rotary encoder is proposed for long-range spectrum analysis and can achieve a high resolution simultaneously. The encoder-based spectrometer is composed of a source, a beam-shaping mirror, a grating disc, and two detection arrays.

Po-Kai Hsieh Study of Servo Compensation over Shifting Volume Holographic Disc
Po-Kai Hsieh;Yeh-Wei Yu;Ching-Cherng Sun

In this paper, we propose a scheme to compensate the position error so that the reading of the holographic disc can be on the correct position and to prevent from large decay of the signal.

Wen-Tse Shih Holographic Lithography on Modulated Nanowire Photonic Crystals
Wen-Tse Shih;Mei-Li Hsieh;Shawn-Yu Lin

We proposed a hybrid technique with holographic lithography to fabricate the modulated nanowire photonic crystal. By modifying the 1D or 2D structure along the vertical direction, the modulated nanowire structure can be easily fabricated, which provides a simple, low cost, and large area maintainable process.

Cheng-Hao Tsou Synthetic-Aperture Hologram Recorded by Optical Scanning Microscopic Holography
Cheng-Hao Tsou;Jung-Ping Liu

Optical scanning holography (OSH) is a scanning-type digital holographic imaging technique. In this paper, we proposed to use OSH to record holograms of micro-specimen. We also applied synthetic-aperture holography to the holograms recorded by OSH. The field of view and the resolution of the hologram can be significantly improved.

Chien-Yu Yu Stereoscopic Computer-Generated Hologram Based on Lookup Table Algorithm
Chien-Yu Yu;Sung-Lin Lu;Jung-Ping Liu

Stereoscopic computer-generated hologram can provide accurate depth cues for three-dimensional display but take a long computing time. Hence, we proposed to use look-up table instead of directly point-by-point computation to significantly reduce the computing time. Meanwhile, the problem of artifacts arose in using lookup table is discussed and solved.

Nikolay V. Petrov Time-resolved in-line digital holography for the measurement of the nonlinear refractive index
Nikolay V. Petrov;Sergey S. Nalegaev;Igor A. Shevkunov;Andrei V. Belashov;Sergei E. Putilin;Yu-Chih Lin;Chau-Jern Cheng

In-line time-resolved digital holography layout under conditions when the pump beam falls on the sample at an acute angle are analyzed. Comparing the value of modulation for a series of samples consisting of materials with known and unknown nonlinear properties makes it possible to determine the nonlinear refractive index.
