This transform allows for generating complex-valued functions from modulated intensity patterns, including high frequency components from modulation, without the generation of unstable phase singularities. From these complex-valued functions it is possible to obtain intensity and pseudo-phase maps to analyze the intensity recordings without the necessity of phase retrieval techniques. The intensity and pseudo-phase maps obtained by using this transform preserve the modulation structure onto the intensity and phase modulo 2? maps, including stable phase singularities. ©2013 Optical Society of America.enghttps://v2.sherpa.ac.uk/id/publication/issn/1094-4087info:eu-repo/semantics/articleModulationOptical phase conjugationComplex valued functionsFrequency modulatedHigh frequency componentsIntensity patternsModulation structurePhase retrievalStable phaseUnstable phaseVortex flow2021-04-12Sierra-Sosa, DanielAngel-Toro, LucianoBolognini, NestorTebaldi, Myrian10.1364/OE.21.023706
