A strong adaptable autofocusing approach of off-axis digital holography

An innovative autofocusing criterion for the reconstruction of digital holograms. This criterion has extremely great adaptability under different quality conditions of holograms.Even for hologram degraded by destructive interference, our method still performs well.We are sure that this technology can do great help in real world applications.
