Abstract

Holographic display based on the computer-generated holograms (CGH) has been suffered from two problems. The first problem is the heavy computational complexity involved in the generation of CGH, which has limited real-time holographic display. The second problem is that the image quality of holographic display is limited. To solve the two problems, a block-based sub-hologram (BSH) method is proposed, which has the ability to generate high quality holograms in real-time. In the BSH method, the target 3D scene is divided into a series of blocks. A block is composed of adjacent object points. We use a diffraction-based approximation method to determine the region of the sub-hologram (SH) corresponding to each block. Since the size and the complexity of the SH are reduced, the computation time is decreased significantly. It is confirmed that the proposed method implemented on the GPU framework can achieve real-time color three-dimensional holographic display with large size.
