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.
