Research of a High-Resolution Volumetric 3D Display System

A high-resolution volumetric 3D display system has been developed, which provides a new viewing modalities for 3D imaging, unlike traditional stereoscopic displays. By ¿volumetric 3D display¿, we mean that each ¿voxel¿ in the displayed 3D images locates physically at the (x, y, z) spatial position where it supposes to be, and emits light from that position to form real 3D images in the eyes of viewers. We have demonstrated the feasibility of our system design by building full-scale prototypes and achieved a large display volume, true volumetric 3D display system with a high resolution of over 100 million voxels in a portable, unique double helix screen design. Meanwhile, to solve the problems of mass-data transfer and storage of three dimension image, a plan combined algorithm for image reconstruction in multi-slice helical image and optimization process method is proposed. It shows that the system possesses the capacity to display complicate true 3D image with clear profile in real space on the base of comparison of experiment results, and the scheme is of favorable feasibility.
