Abstract
An additional step to traditional iterative phase retrieval algorithms is described that allows the reconstruction of an image from the product of its sufficiently sampled far-field diffraction intensity and a second signal. The iterative phasing algorithm with this added step attempts to recover both the image and the multiplicative signal at the same time. Simulations show that reasonable reconstructions of both the original image and the multiplicative signal can be attained in many cases.
