摘　　要：In terms of the cascading property and additivity of the order of the fractional Fourier transform, a new recursive algorithm is presented to implement phase retrieval from intensity measurements in the Fourier transform domain. This approach simplifies significantly computational manipulations compared with conventional iterative algorithms.In terms of the cascading property and additivity of the order of the fractional Fourier transform, a new recursive algorithm is presented to implement phase retrieval from intensity measurements in the Fourier transform domain.
