3D display
Volumetric displays present volumetric images that can be directly observed by humans by generating three-dimensional pixels (voxels) in physical space. A gas-excited volumetric display has been proposed, in which a gas is excited by a focused pulsed laser and its emission is used as voxels. It achieved touch interaction using a seamless relationship between the user and the image and voxel coloration by selectively extracting the emission color of the plasma covering the visible region.
In this study, we evaluate the image rendering range and voxel luminescence characteristics of volumetric displays when the image size of the order of centimeters is achieved by reconstructing the optical system. We have evaluated the light intensity and emission size of voxels produced by focused femtosecond laser irradiation into air by changing the position of the light source.
