Abstract
En 中文
To develop a volumetric display of the kind we see in science fiction movies is a dream of many display researchers, including us. Here, we show a new volumetric display with microbubble voxels. The microbubbles are three-dimensionally generated in liquid by focused femtosecond laser pulses. The use of a high-viscosity liquid, which is a key part of the development of this idea, slows down the movement of the microbubbles, and, as a result, volumetric graphics can be displayed. This volumetric bubble display has a wide-angle view, simple refreshing, and no addressing wires, since the transparent liquid is accessed optically rather than electronically. It achieves full-color graphics composed of light-scattering voxels controlled by illumination light sources. Furthermore, a holographic laser drawing method based on a computer-generated hologram displayed on a liquid-crystal spatial light modulator controls the light intensity of the microbubble voxels with an increase in the number of voxels per unit time and the spatial shaping of the voxels.
