英文摘要：

Three-dimensional（3D） holographic imaging is a technique to generate cubic images with holography.A 3D object can be divided into a series of two-dimensional slices along the optical axis.With an efficient and fast three-dimensional Gerchberg-Saxton algorithm,phase-only Fourier holograms for 3D objects is generated.Then the holograms are loaded onto a liquid crystal spatial light modulator and the 3D light fields along the optical axis are obtained.The light fields are explicit and coherent,with high contrast and low noise.This technique is applicable in medicine,military,3D display,micromachining and micro-technology.
