Abstract

We propose an updatable volumetric display rendered by microbubbles induced by holographic femtosecond laser drawing using computer-generated holograms displayed on liquid crystal spatial light modulator and ultrasonic vibrator to refresh the graphics. We have made the system that consists of a femtosecond laser, a 3D beam scanner, a spatial light modulator and a glycerin. We have conducted experiments of observation shapes of microbubbles, rendering and erase the bubble graphics.
