摘要

为了优化固态体积式真三维的立体成像效果

显示出更加逼真的立体图像

对编码图像的灰度级和成像显示体的对比度进行了研究。论文从固态体积式真三维立体显示器成像原理出发

介绍了固态体积式真三维的电路系统、光学投影系统和成像显示体

在分析和研究影响立体显示效果的主要因素后提出了两种改进的方法。一种方法是通过降低图像刷新频率

提高编码图像数据位数

从而提高像素灰度等级

另一种方法是改变液晶光阀的盒厚

以此增强显示体的对比度。在真三维样机上

成功实现了32级灰度

将颜色种类从4 096种提升至32 768种

对比度相比原样机提高了1.2倍

主观感受到更加丰富的图像细节和色彩。优化效果明显

可以显示出细节更加清晰、颜色更加丰富和效果更加真实的三维立体图像。

Abstract

In order to optimize the effect of solid-state volumetric true 3D display and show even more realistic 3D images

this paper researched the grayscale of coded images and the contrast of display volume. The paper introduces solid-state volumetric true 3D display's circuitry system

optical projection and the imaging display volume

according to the imaging principle of solid-state volumetric true 3D display. After analyzing and studying the main influences on the effect of 3D display

we come up with two methods to improve it. One way is reducing the image refresh rate and increasing the number of encoded image's bits to improve the pixel's gray level. Another method is changing the thickness of the liquid crystal light valve to enhance the contrast of the display volume. On the model machine of true 3D display

we not only succeed in achieving 32 levels of grayscale to increase the range of color from 4 096 to 32 768 and improve 1.2 times on contrast compared to the original model machine

but also can feel richer details and colors in image. The optimizing effect is obvious

and it make the machine show the details much clearly

the colors richer and the effect of 3D images more realistic.
