Abstract

For the control and further improvement of applications concerning the orbital angular momentum (OAM) of light the detailed knowledge about the properties of the used OAM beam is required. We present a detailed analysis method for vortex beams carrying OAM, which is based on an all optical holographic correlation filter technique. For this purpose, the beam is decomposed into a complete and orthogonal set of vortex modes, which enables the real-time determination of the underlying OAM state spectrum, of total OAM , OAM density distribution and position of occurring phase singularities.
