目前主要影响体三维成像质量的因素之一是死区，为此，基于体三维静态成像机理，针对国内现有体三维静态成像系统中存在的各种死区问题，如视觉死区、体素重叠死区、体素变形死区等，分析了各种死区成因，并相应给出了一些削弱死区影响的解决措施，如采用一体化背面投影光路结构设计、旋转螺旋屏成像的方式等，以便获得高清晰图像。最后在研究结果的理论支持下，构建了一种体三维显示系统。实验结果表明，该系统可以很好的削弱死区影响，获得高质量成像效果。

Now, one of the main factors influencing the high resolution image is the dead zone. Firstly, based on the current static Volumetric 3D Imaging (V3DI) display systems, the imaging principles are described. And then, several reasons for dead zone existing are analyzed in detail, such as visual dead zone, voxel overlapping dead zone and voxel distortional dead zone et al. Meanwhile, in order to get a high resolution image, some effective approaches to solve these problems are given, such as structural design of integrated beam-splitter folded path for rear projection displays, imaging method based on rotating helix screen. Finally, a novel V3DI display system is built with the support of the theory of studying results. The experimental results show the system can weaken the dead zone effect, and acquire very high image quality.
