主 题:Fourier holography digital amplitude hologram iterative Fourier transform algorithm iterative stepwise binarization hologram domain object domain constraints energy factor
摘 要:We propose a method for optimizing the process of iteratively binarizing digital amplitude holograms by utilizing the effect of adding energy to the reconstructed signal window from the hologram. For this purpose, we introduce a parameter called the energy factor and show that the performance of the iterative binarization process can be greatly enhanced if the value of the energy factor is properly chosen. Finally, we show that the optimal values of this energy factor can be estimated with an analytical function for different computational costs.
