An approach based on the two-channel moiré deflectometry has been used to measure both wavefront and transverse component of the Poynting vector of an optical vortex beam. Generated vortex beam by the q -plate, an inhomogeneous liquid crystal cell, has been analyzed with such technique. The measured topological charge of generated beams are in an excellent agreement with theoretical prediction.

Abstract
An approach based on the two-channel moiré deflectometry has been used to measure both wavefront and transverse component of the Poynting vector of an optical vortex beam. Generated vortex beam by the q -plate, an inhomogeneous liquid crystal cell, has been analyzed with such technique. The measured topological charge of generated beams are in an excellent agreement with theoretical prediction.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
