3次元配置した微小領域でのレーザ光拡散を利用した多視点裸眼立体視ディスプレイの開発

Abstract

Standard flat screen 3D displays such as 3D-televisions use parallax to replicate spatial effect withinthe plane. However, such types require wearing special glass-like equipment and both viewing angle and totalnumber of viewers are very limited. Thus, the present paper proposes a new 3 dimensional display named“LuminantCube”, which is able to provide omnidirectional and auto-stereoscopic views, meaning that there are nolimitations of viewing angle and number of simultaneous viewers and can achieve stereo vision with naked eyes.LuminantCube, consisted of glass cube and a laser pico-projector, uses diffusion of lights projected from theprojectors, caused within a volumetrically arranged micro voids processed numerously and randomly inside thecube. Currently, there are 3600 pixels inside LuminantCube and an original middleware and calibration algorithmare installed for projecting 3D contents. In the future, LuminantCube will be able to achieve higher resolution andcontrast ratio by optimizing the algorithm of converting projector pixel to display pixel for multiple projectors forthe former and overlapping multiple light rays for each individual micro voids for the latter.
