A new method of making three-dimensional hologram is presented.On the basic principle of two-step rainbow holography,we obtain the Fraunhoer phase information of three-dimensional object by digital coding the wave front of multi visual angle images.Such images are divided into small blocks and coding individually.In the experiments,the phase information of blocks was inputted into phase only liquid crystal on silicon spatial light modulator,the voxel image was reconstructed at the focal plane of fourier lens with laser ilumination and recoded with interference on photoresists.The whole three-dimensional image was obtained by matrix stitching voxel images.The results proved this mehtod.It will be an important technology of three-dimensional display.
