Abstract

A scanning imaging system is proposed that is capable of reconstructing not only the modulus but the phase of an object without a holographic reference wave. The reconstruction involves phase retrieval from two intensity measurements: the intensity of the correlation function of the object and a probe beam and the intensity of the correlation function of the object and the probe beam that is modulated with an exponential filter. A computer simulation shows that the reconstruction of a complex-valued object can be done from a relatively small data set.
