At the same time, the 3D display has improved the display mode of 2D image and offered stronger ability to reproduce the true image. For the needs of large size, light and thin, and high-quality in the modern display technology, undoubtedly the 3D image transmitting the new-type attitude of information, and also build the more high-level perspective for the display technology in the future. 3D technology has been already extensively applied in many fields like military, medical science, education, and exhibition. The quality demand for the 3D image differs widely in different ranges of application. One design method of the 3-D stereoscopic display system is based on polarization separation of the binocular parallax images. Usually two orthogonal linearly polarized lights are used in such a system, however it suffers from cross-talk between the binocular parallax images in case of tilting the viewer’s polarization glasses. In this paper, we introduce a stereoscopic rear projection display system based on circularly polarized lights to circumvent the drawback of the conventional system. Furthermore, we use a broadband retarder, which is designed by a direct binary search (DBS) algorithm, to provide chromatically non-dispersive stereoscopic images. This method can be designed for high performance stereoscopic requirements such as in those systems for medical application.Contents 摘要 I Abstract II 誌謝 III Table of Contents IV List of Figures VI List of Tables IX Chapter 1 Introduction 1 Chapter 2 Fundamentals and Literature Reviews of 3D Display 2.1 Human depth perception 3 2.1.1 Monocular and oculomotor depth cues 3 2.1.2 Binocular depth perception in the natural world 6 2.1.3 Summary 9 2.2 Reviews of 3D display technologies 10 2.2.1 Stereoscopic systems 10 2.2.2 Autostereoscopic systems 14 Chapter 3 Dispersion-Free Stereo Rear-Projection Display 3.1 Theoretical design of the stereo rear-projection display 22 3.2 The theory of the polarization beam splitter 24 3.3 Design of the broadband retarder 28 3.3.1 Principle of birefringence material 28 and retardation plate 3.3.2 Jones matrix and Jones vector 32 3.3.3 Direct binary search algorithm 34 3.3.4 Simulation analysis and experimental results 42 of broadband retarder Chapter 4 Conclusion 671665880 bytesapplication/pdfen-US立體顯示器寬頻帶波板雙眼視差色散stereoscopic displaybroadband retarderparallax imagescolor dispersionthesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/50832/1/ntu-95-R93941037-1.pdf
