    Abstract
    An approach based on the two-channel moir頤eflectometry 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.An approach based on the two-channel moir頤eflectometry has been used to measure both wavefront and transverse component of the Poynting vector of an optical vortex beam.
