Image process of 3D reconstruction from holograms

A method to extract the information of a 3D object from the hologram is proposed with the application of the combination of computer and hologram. Simulated holograms of point object and 3D body-centered cubic lattice are made by overlapping the parallel reference coherent light. By means of FOurier optical analyze method, the objects were reconstructed successfully from the simulated hologram with object aberration less than 6.25 percent. FFT technology is used to quick the process.
