TA would like to acknowledge the financial support from Secretaría de Estado de Educación y Universidades (SB2000-0166), the Spanish Ministry of Education, Culture and Sport.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.engjournal articlehttp://dx.doi.org/10.1088/0305-4470/35/36/306http://iopscience.iop.orgopen access535TransformConvolutionÓptica (Física)2209.19 Óptica Física
