In this work, demonstrate an efficient method for measuring the orbital angular momentum of optical vortices. This method, based on a multipinhole interferometer and phase extracting from the Fourier transform of a multipinhole diffraction intensity pattern with a simple image processing. Using this method the optical angular momentum of the photon can be measured quantitatively.
