Particle swarm optimization algorithm for reconstruction of parallel phase shifting digital holography

Parallel phase-shifting digital holography records a single shot hologram with different phase values. To obtain complex amplitude multiple holograms are needed from a single shot hologram. To extract these holograms weighted interpolation technique is used and the weights are calculated by using Particle Swarm Optimization (PSO). The algorithm is based on a new objective function that has been proposed for achieving desired efficiency. So the quality of the reconstructed hologram can be enhanced by reducing the phase error and calculation error.
