Scientific paper

Diffraction-limited images can be reconstructed from Fourier intensity data despite severe phase errors or even total loss of phase information, as presently revealed for the cases of active, coherent imaging, passive, incoherent imaging, and incoherent imaging from multiple realizations of coherent intensity data. The latter two modes allow a nonnegativity constraint that greatly facilitates the reconstruction process. For those cases in which the support constraint is not known a priori, a method is illustrated for determining the upper bounds on the object's support from its autocorrelation support.
