Paper Abstract

A three-dimensional display using persistence of vision (POV) has its own benefits for natural image expression. Conventional POV display using light emitting diode (LED) array was connected with a high speed motor, so it could be possible to express curved-type two-dimensional display or volumetric three-dimensional display. However, it is necessary to consider interactive three-dimensional display. For example, this kind of volumetric display is hardly applied on interactive display since light emitting parts are placed in the center of a rotating screen. To provide a complementary effort to this need, we propose here a hologram-like interactive volumetric display using LED array type persistence of vision and a pair of parabolic mirrors. We build the volumetric POV display by using small size LED arrays. This POV display is located below a pair of parabolic mirrors so the mirrors make hologram-like volumetric POV images to be reimaged such as 4f system of lenses. Several preliminary experiments will be provided for our proposed method.
