Mapping phases of singular scalar light fields

Denisenko, Vladimir G.; Minovich, Alexander; Desyatnikov, Anton S.; Soskin, Marat S.; Krolikowski, Wieslaw; Kivshar, Yuri


We implement experimentally a simple method for accurate measurements of phase distributions of scalar light fields. The method is based on the polarimetric technique for recording the polarization maps of vector fields, where coaxial superposition of orthogonally polarized reference and signal beams allows the signal phase to be reconstructed from the polarization map of the total field. We demonstrate this method by resolving topologically neutral pairs of closely positioned vortices in a...[Show more]
