Conclusions
We have shown that it is possible to accelerate considerably the computation of phase-only Fourier holograms by using a consumer graphics board (MSI 6800GT) instead of the ordinary CPU. Our fastest CPU solution (Pentium 4 @ 3.0 GHz) — using handcoded assembly code together with the multimedia extensions SSE — was outperformed by a factor of more than thirty resulting in an average performance of 14.1 GFlops for 100 doughnuts. The presented algorithm can be used for the computation of holograms for an arbitrary (up to 250) number of traps located at different positions in three dimensions and having independent trapping potentials.
We thank the Landesstiftung Baden-Württemberg for their financial support within the project “AMIMA”.
