基于螺旋旋转屏和数字微镜元件(Digital micro-mirror device,DMD)技术,对原体扫描显示系统原型进行了改进.采用螺旋旋转屏构建体扫描显示系统的成像空间,可改善平面旋转屏体扫描系统中存在的成像空间较小、体素数量较少和体素重叠死区严重等缺陷.利用DMD空间光调制技术,在体素激活子系统中提高了三维数据传输的带宽,达到同时激活多个体素的目的.研制了基于螺旋旋转屏和DMD的体扫描显示系统原型.实验结果表明,所设计的系统原型与前期平面旋转屏系统相比,在成像空间、视觉死区、切片上的体素数量及体素激活能力等方面都有所改善.

Based on the helix rotating screen and the digital micro-mirror device(DMD),the former proto of volumetric-swept display system is improved.The 3-D display system adopting a helix rotating screen to construct an imaging space meliorate the defects,such as the smaller image space,the fewer voxels and the severer voxel overlap dead zone caused by planar rotating screen.DMD with spatial light modular (SLM) technology increases the transmission bandwidth of 3-D data in the voxel activation subsystem and activate multi-voxel once time.The volumetric-swept system based on helix rotating screen and DMD is developed.The experimental results show that the image space,the vision dead zone,the voxels on slice,and the voxel activation capacity of the designed proto are superior to the plane rotating screen system.
