Real-time electro-holography with parabolic mirrors for projecting floating 3D motion pictures

Aerial projection is a remarkable and promising technique for a lot of fields such as digital signage, amusement, entertainment, business scene, and so on. This is because floating images by aerial projection system can attract viewers. In particular, floating 3D motion pictures make impressions on viewers. Although there are many techniques to project floating 3D motion pictures, they require multiple projectors or mechanical rotating and scanning processing to project floating 3D images. Then we proposed and demonstrated an aerial projection system based on electroholography which can reconstruct 3D images without multiple projectors and mechanical processing [Kakue et al. 2015]. Although we achieved real-time reconstruction of 3D images in previous study, we only focused on acceleration of calculation. In this work, we aim to realize interactive reconstruction of floating 3D motion pictures by the electro-holographic display.
