We developed a glasses-free 3D stereoscopic display using an LCD display panel, a view control film and a grating film for stereoscopic viewing. The observer can watch overlapped stereoscopic images for left and right eyes without special glasses such as polarized glasses.

It was known that chalcogenide glasses have the superior property of the photoinduced anisotropy(PA). In this study we observed the phenomenon of Ag polarized-photodoping in chalcogenide As$_{40}$ /Ge$_{10}$/Se$_{15}$ /S$_{35}$ and the double-layer of Ag doped As$_{40}$ /Ge$_{10}$/Se$_{15}$ /S$_{35}$ thin film using the irradiation with the polarized He-Ne laser light. The Ag polarized-photodoping results in reducing the time of saturation anisotorpy and increasing the sensitivity of linearly anisotropy intensity up to maximum 220% The Ag polrized-photodoping shows improvement of the photoinduced anisotropy property in polarized photodoping of the chalcogenide thin film. It will offer lots of information for the photodoping mechanism and analysis of chalcogenide thin film.in film.ilm.

현재 상용화된 대부분의 3D 디스플레이는 왼쪽 눈과 오른쪽 눈의 입력영상을 다르게 만들어 입체감을 만드는 양안시차 방식을 적용하고 있다. 하지만 상용화된 3D 영상 출력 장치는 성능 부족에 의한 시청자의 불편 유발과 시청위치의 제약 등의 문제들이 있다. 본 논문에서는 기존 Dual-cell 구조 대비 시야각, Crosstalk 감소, 광투과도를 향상할 수 있는 Single-cell 구조의 편광안경식 입체영상 시스템을 개발하고, 투과도 실험과 시야각 평가를 통해 Single-cell 구조의 편광안경식 입체영상 시스템 특성분석과 Dual-cell 구조 대비 성능향상 효과 분석을 진행하였다. 분석 결과 Single-cell 구조가 Dual-cell 구조 대비 투과도 부분에서 약 25% 이상의 높은 성능을 보이며, 시야각 평가 중 입체 영상 특성품질의 주요지표인 3D crosstalk 지표는 약 37% 이상 향상되는 것을 확인할 수 있었다.

The chalcogenide glasses of thin films have the superior property of photoinduced anisotrophy(PA). In this study, we observed the linear dichroism(D) using the irradiation with polarized He-Ne laser light, in the $Ag/As_{10}Ge_{10}Se_{15}S_{35}$ multi-layer.

Chalcogenide glasses are suggested as a candidate for optical recording. In this study, we have investigated the holography recording and reconstruction of the polarization state in chalcogenide As$_{40}$ Ge$_{10}$Se$_{15}$ S$_{35}$ thin films. We have used a He-Ne laser light(633nm) to probe and record of the grating. Also the polarization state of object beam was modulated with a λ/4 wave plate. The polarization state of the +1st order diffracted beam was generated by readout of the grating with a linearly polarized reference beam. It was the same-handed polarization state as the polarization state of the recording beam. The result is shown that the diffraction efficiency of circularly polarized recording represents higher than other polarization state.ate.e.

Amorphous chalcogenide glasses have a wide variety of light-induced effects. In this study, we have investigated the diffraction efficiency of chalcogenide. As$_{40}$ Ge$_{10}$ Se$_{15}$ S$_{35}$ thin films by the various applied electric fields. The holographic grating in these thin films has been formed using a linearly polarized He-Ne laser light (633nm). The diffraction efficiency was investigated the two method of applied electric field in the perpendicular and parallel to the direction of inducing beam. We obtained that properties of diffraction efficiency in the two methods of applied electric field. The result is shown that the diffraction efficiency of parallel electric field is 285% increase, η=1.1$\times$10$^{-3}$ and the diffraction efficiency of perpendicular electric field is 80% decrease, η=9.83$\times$10$^{-5}$ . Also, we have investigated the anisotropy property on chalcogenide thin films by the electric field effects.
