A fast computer simulation solution for rainbow hologram reconstruction based on GPU is proposed. In the commonly used segment Fourier transform method for rainbow hologram reconstruction, the computation of 2D Fourier transform on each hologram segment is very time consuming. GPU-based parallel computing can be applied to improve the computing speed. Compared with CPU computing, simulation results indicate that our proposed GPU computing can effectively reduce the computation time by as much as eight times.
