For 3 D images produced by the two former V3 D imaging systems are unclarity,a high resolution,passive rotating sweep V3D imaging system based on digital micro-mirror device and double helically-curved screen is put forward and realized.The composition and principle of the system are introduced,and the hardware design and software algorithms of image space,voxel activation device and V3D engine are described in detail.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.Experimental result 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.
