Digital Holography and Microscopy

We are studying electronic holography and have developed a real-time color holography system for live scene which includes three functional blocks, capture block, processing block, and display block. In this paper, we will introduce our developed system after describing basic idea that quickly calculates hologram from IP image. The first block, capture block, uses integral photography (IP) technology to capture color 3-D objects under natural light in real time. The second block, processing block, consists of four 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 all captured IP images by using fast Fourier Transform. The last block, display block, mainly consists of three liquid crystal displays to display the holograms and three laser sources for RGB to reconstruct the color 3-D objects. All blocks work in real time, i.e., in 30 color frames per second.
