【摘要】：固态体积式真三维显示技术将附有深度信息的立体图像切片投影至对应深度的显示体中,根据人眼的视觉暂留效应,形成具有真实物理景深的空间图像,具有直接观看、宽视角、大色域等特点。固态体积式真三维显示的技术优势使其成为立体显示领域最佳解决方案之一,并被更多潜在用户所青睐。本文首先介绍了常见的立体显示技术,并概括其国内外的发展状况。然后根据固态体积式真三维显示器的系统组成,介绍了采取的技术路线。固态体积式真三维显示器采用高速DLP光学引擎,依据真三维显示器的性能要求,设计高亮度的4UHP光源系统,并采用复眼均光系统实现均匀照明。设计新型态TIR棱镜,提升真三维显示器的对比度。为解决各层画面之间的面积差,保证机身合理尺寸,设计具有较大后工作距的短焦投影镜头。采用四片反射镜折叠光路,减小了机身尺寸。设计了样机中各功能部分的机械结构。根据光学引擎和机械结构设计,完成40寸固态体积式真三维显示样机的开发,并对真三维系统做了实际演示与性能测试。系统演示结果表明,真三维显示器具有较好的三维画面显示效果,画面立体感较强,无明显分层现象,具有真实的物理景深,真正实现了空间物体的再现。样机的主体结构设计以及辅助性设计的稳定性较好,显示器可实现正常、稳定、长时间工作。设计的高速光学引擎完全适用于40寸固态体积式真三维显示器样机。
[Abstract]:Solid volume true 3D display technology projects stereoscopic image slice with depth information to the display body with corresponding depth. According to the visual temporary effect of human eyes, it forms a spatial image with real physical depth of field, which can be viewed directly.Wide angle of view, large color gamut and other characteristics.Solid volume true 3D display technology makes it one of the best solutions in stereoscopic display field and is favored by more potential users.This paper first introduces the common stereoscopic display technology, and summarizes its development situation at home and abroad.Then according to the system composition of solid-state volume true-three-dimensional display, the technical route is introduced.High speed DLP optical engine is used in solid volume true 3D display. According to the performance requirements of true three dimensional display, a high brightness 4UHP light source system is designed and uniform illumination is realized by using compound eye equalization system.A new type of TIR prism is designed to enhance the contrast of true 3D display.In order to solve the area difference between different layers and ensure the reasonable size of the fuselage, a short focus projection lens with large working distance was designed.Four mirrors are used to fold the light path to reduce the size of the fuselage.The mechanical structure of each functional part of the prototype is designed.According to the design of optical engine and mechanical structure, the 40-inch solid solid volume true 3D display prototype is developed, and the real 3D system is demonstrated and tested.The system demonstration results show that the true 3D display has a good effect of 3D picture display, the picture has a strong three-dimensional sense, there is no obvious stratification phenomenon, and it has real physical depth of field, which can truly realize the reappearance of space objects.The stability of the main structure and auxiliary design of the prototype is good, and the display can work normally, stably and for a long time.The designed high-speed optical engine is suitable for 40-inch solid-state solid-state true 3 D display prototype.
