Abstract
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.
