Abstract
This paper presents the development of a swept-volume
display system using three screens. Experimentally, 3D image is refreshed
900 times when the motor runs at the speed of 300 rpm. The image volume is ${\hbox{480}} ~{\hbox{mm}}\ast {\hbox{360}}
~{\hbox{mm}}\ast {\hbox{360}}~{\hbox{mm}}$ and the image resolution
is ${\hbox{1024}}\ast {\hbox{768}}\ast
{\hbox{750}}$. In addition, we also developed a parallel moving
swept-volume mechanical system based on structure of planetary gear to increase
regularity of three-dimensional (3D) images, reduce the noise of mechanical
rotation and remove visual dead zones on central axis at any viewing angle.
Through the simulation and measurement of the screen deformation, the sampled
light slice is corrected and a 3D image acquiring method based on virtual
light slice is proposed. Demonstrated in the experiments, a prototype of this
system is able to display 3D image with the brightness up to 70 lum, also
generate almost 590 million voxels and well-distributed 3D images. The motor
speed of parallel moving swept-volume system is 1/3 the speed of rotating
swept-volume system. The prototype only produces noise levels of 60 dB.
