Three-dimensional Holographic Display using Dense Ray Sampling and Integral Imaging

In this paper, we overview a high resolution three-dimensional (3D) holographic display using 2D images captured in an integral imaging system and dense ray resampling technique. Holograms are generated the resampled rays from the 2D images. This method can improve the display resolution because each object is captured in focus and light-ray information is interpolated and resampled with high density on ray-sampling plane located near the object. Numerical experimental results for different scenes show that the presented holographic display technique can reconstruct multiple objects at different depths with higher resolution compared to conventional integral imaging-based holographic displays.
