Three-Dimensional Holographic Display Using Dense Ray Sampling and Integral Imaging Capture

We present optical experimental results for a high-resolution three-dimensional (3D) holographic display system based on dense ray sampling and integral imaging capture. Holograms are generated based on re-sampling the rays from 2D images captured by an integral imaging system. In addition, we demonstrate a depth of field extension technique during the integral imaging capture by combining an amplitude modulated lens technique and a blind convolution approach. The optically reconstructed images of the holographic display system are shown and compared with conventional integral imaging-based holographic displays for different scenes.
