The Wavefront Engineering Group (Department of Applied Physics, Universitat de Barcelona) is a research unit centered on study of a variety of problems on Physical Optics. We mainly concentrate on the development of theoretical design and experimental implementation of electromagnetic highly focused fields with unconventional behavior in terms of their polarization and coherence properties. Complex amplitude and polarization are manipulated by means of computer generated holograms displayed on spatial light modulators.

Circularly focused beam

Optical security problems using randomly polarized beams is also one of our priorities. Both problems on optical authentication using machine learning or convectional optical encryption using focused beams are considered. Moreover, we also face problems on 3D imaging. The use of integral imaging techniques is very appropriated to deal with the measure of polarized light in both conventional and low light conditions
