Abstract

This paper introduces optical vortex metrology, that makes use of the phase singularities in the pseudophase of the complex signal obtained from the Riesz transform or the Laguerre-Gauss transform of speckle patterns.Here, this paper reviews the principle and demonstrate how effective use can be made of optical vortices or phase singularities for displacement , flow measurements and biological kinematic analysis.
