自由立体显示中的背光系统设计

摘要

为实现自由立体显示，提出了一种新型指向性背光结构，配合人眼跟踪系统，分时显示具有视差的立体图像对，基于视差原理实现了高清分辨率的多用户自由立体显示。着重阐述了多光程结构、菲涅尔透镜以及掠入射的光路系统，以及从这三方面产生的效果。实验表明，三者的结合能产生良好的背光效果，最终实现了具有较强立体感的无分辨率损失的自由立体显示。%In order to realize autostereoscopic display,a new directional optic structure was proposed by providing a pair of parallax images time-sequentially. Aided with the human eye tracking system,a high resolution multi-user parallax 3D displayer was invented.The multi optical path sturcture,fresnel lens,grazing incidence and their results were elaborated. As the experimental results shows,the combination of the three sturctures can generate strong backlight effect,and finally a strong 3D visual sense is achieved without loss of resolution.
