摘要

We report on an improvement of the voxel density of three-dimensional (3D) image display by spatially multiplexing fluxes in light-ray-flux reproduction method. In the basic light-ray-flux reproduction method, a color filter is projected by the use of an array of white-color point light sources in order to artificially generate a group of light rays corresponding to light scattered from an object, to thereby generate a 3D image. In the developed system, we used liquid crystal display (LCD) and pinhole array instead of color filter and white-color point light source array. The principle of this modified system is the same as the basic system. The light-ray fluxes are spatially multiplexed by rapidly changing the position of the pinholes. The 2D filter images displayed by the LCD are changed in synchronized with the position changes of the pinholes. In the experiment, position changes of the pinholes are realized by mechanically vibrating a slit mask array, which covers the pinhole array. We confirmed that the voxel density was improved to twice without the degradation of the viewing angle and the depth of the reconstructed 3D image.
