Image Processing of Optical Vortex and Determination of OAM

Abstract

This study aims to analyze the transverse spatial profile of the intensity of optical vortex patterns which have been produced by using fork hologram and spatial light modulator. The properties of intensity distribution has been investigated by using image processing technique. The results will be very useful to understand the change of the intensity profile and the value of orbital angular momentum of optical vortex patterns which are obtained experimentally.
