Abstract

A volumetric display generates three-dimensional (3D) graphics consisting of voxels in real space. It is a promising scheme of the volumetric displays to draw the voxels by 3D scanning of laser focusing points. The laser drawing method supports a wide viewing angle because these is no physical wiring between drawing space and the graphics forming system. The graphics size was ~ 1 cm³ in our previous research. In order to enlarge the volumetric bubble displays, the scan range should be increase with an objective lens with a long focal length. However, the increase gives an increase of the focusing diameter that requires an increase of the excitation energy. It is demonstrated that the use of gold nanoparticles was to decrease the excitation energy of the microbubbles.
