摘要
立体显示技术的研究主要是解决虚拟现实领域的三维视觉问题。自动立体显示是不需要配戴特殊眼镜的,使用一个二维平面空间显示屏显示至少一对满足双眼视差的立体图像。当人的双眼接受到具有视差的立体图像对时,在视网膜上形成视差像,经大脑神经系统的融合,从而产生深度感。提出了一种全新的实现自动立体显示的折射式方法,设计了基于此方法的一种新型折射式的、结构简单的、通过透射显示屏(如液晶显示屏)实现自动立体显示的背光系统。根据视差立体显示参量模型,建立了光学系统的结构参量以及分析了光学材料的性质对实现立体显示的影响,并运用先进的光学设计软件进行设计、模拟。
Three-dimensional display is a visual part of virtual-reality system. Autostereoscopic display is a significant category of three-dimensional display. It can present each viewer at least a pair of stereoscopic three-dimensional image without special glasses. When either eye sees one of a pair of stereoscopic images respectively, through the fusion of brain neural system, human can perceive depth. In this paper, a new method for autostereoscopic display is proposed, and based on it a novel refractive, simple backlight using transparent display screen, like LCD panel, is designed to implement autostereoscopic display. The authors establish optical parameters of the backlight, analyze optical material characters that are critical to the realization of autostereoscopic display, and conduct design and simulation of the display system using ASAP optical modeling software.
