Abstract

A new type of omnidirectional-view 3D display is proposed, which is composed of a rotating selective-diffusing screen and multiple mini-projectors. A selective-diffusing screen using two field lenses and one lenticular is developed and analyzed. A rotation aperture pupil structure is designed to ensure the accurate synchronization between the projectors and the rotating screen. Correct 2D images are projected on the screen by different mini-projectors, whereas the screen rotates to form the light field 3D image using the effect of human vision persistence. This method is verified by experimental results, and a touchable vivid color 3D image floating in the space above the system with correct occlusion and smooth parallax is demonstrated by the prototype.
