Abstract
A phase retrieval method 1 using third and fourth order intensity correlations is employed to reconstruct the object. To study the ef feet iveness of the reconstruction technique with estimates of intensity correlations from measured data, we have developed a computer simulation of the light intensity measurement process, In this simulation, the speckle patterns of the object are generated and third and fourth order intensity correlation estimates are formed and used to recover complex spatial coherence function maps. Combining this simulation with the reconstruction procedure we have studied the behavior and efficiency of the end-to-end image reconstruct ion technique.Keywords
