RT Journal Article T1 Power filtering of nth order in the fractional Fourier domain A1 Bastiaans, Martin J. A1 Alieva Krasheninnikova, Tatiana A1 Calvo Padilla, María Luisa AB The main properties of the power filtering operation in the fractional Fourier domain and its relationship to the differentiation operation are considered. The application of linear power filtering for solving the phase retrieval problem from intensity distributions only is proposed. The optical configuration for the experimental realization of the method is discussed.
