Paper Abstract

We are studying electronic holography and have developed a real-time color holographic movie system which includes three functional blocks, capture block, processing block, and display block. We will introduce the system and its technology in this paper. The first block, capture block, uses integral photography (IP) technology to capture color 3-D objects in real time. This block mainly consists of a lens array with approximately 120(W)x67(H) convex lenses and a video camera with 1920(W)x1080(H) pixels to capture IP images. In addition to that, the optical system to reduce the crosstalk between elemental images is mounted. The second block, processing block, consists of two general personal computers to generate holograms from IP images in real time. Three half-zone-plated holograms for red, green and blue (RGB) channels are generated for each frame by using Fast Fourier Transform. The last block, display block, mainly consists of three liquid crystal displays for displaying the holograms and three laser sources for RGB to reconstruct the color 3-D objects. This block is a single-sideband holography display, which cuts off conjugate and carrier images from primary images. All blocks work in real time, i.e., in 30 frames per second.
