As a result, we find a theoretical solution of the inverse problem of image propagation in non-coherent case. However, the practical solution of the inverse problem in a numerical way leads to rapidly decreasing SNR. We also discuss origin and behavior of that phenomenon. Some numerical examples are presented.6 pages, 5 figuresOpticstext
