A procedure to reconstruct sampled complex-valued objects from
intensity data at the output of a general optical system is given. It is shown that
both the choice of the sampling points at the output plane (uniform or nonuniform
sampling) and the specific values of the intensity at these points determine
the uniqueness features of the reconstruction problem.
