title: Introduction.
abstract: Signal recovery and synthesis is concerned with methods for obtaining the best estimate of an image from the data and constraints at hand. It is an area that is important to many fields of optics, as well as a broader constituency due to its interdisciplinary nature; examples include digital image reconstruction from Fourier intensity measurements, superresolution, tomographic reconstruction and deconvolution/deblurring. Applications cover both incoherent and incoherent imaging; crystallography; tomography and inverse scattering.
