These techniques use the advantages of the latest phase retrieval techniques and single pixel (SP) detection to retrieve the complex field. These techniques as a whole form a suitable tool for the characterization of dynamically perturbed scalar beams with singular phase profiles.</p>We propose new techniques for the reconstruction of complex fields through the development of new iterative algorithms based on propagation equations and the representation of complex objects on orthogonal bases.
