One step hologram calculation for multi-plane objects based on nonuniform sampling (Invited Paper)

Chenliang Chang, Jun Xia, and Wei Lei

The nonuniform sampling method in hologram plane is proposed to reconstruct objects on multi-plane simultaneously. The hologram is nonuniformly sampled by decomposing it into several parts with various sampling rates. The hologram is calculated based on the nonuniform fast Fourier transform (NUFFT) algorithm. In the experiment, we load this nonuniformly sampled hologram on phases-only spatial light modulator (SLM), and by illumination with collimated light objects with different sampling rates are reconstructed at different distant planes simultaneously. Both of the numerically simulation and optical experiments are performed to demonstrate the feasibility of our method. The experiment also shows that our proposed nonuniform sampled hologram for multi-plane objects is calculated by only one step, better than conventional method that needs several steps of calculation proportional to the numbers of object planes.
