On a Holographic 3D Screen Display using Scattering of Particles

Abstract

Holographic process is an imaging technique for reconstructing 3D images in three dimensional space. In holographic wave front reconstructing, several approaches adopting photorefractive crystals or lens systems have been studied. However in these systems, the problems arise such that the size of the reconstructed image is to be small and the visual field is restricted to be narrow by the lens. Our new imaging process presented here takes advantage of scattering of particles (by spraying water) as a holographic 3D screen, and this process enables us to reconstruct relatively larger 3D images (5cm×5cm) than the ones (1.5cm×1.5cm) observed in the previous systems
