Quantitative measurement of the orbital angular momentum density of light
Applied Optics, 2012In this work we derive expressions for the orbital angular momentum (OAM) density of light, for both symmetric and nonsymmetric optical fields, that allow a direct comparison between theory and experiment. We present a simple method for measuring the OAM density in optical fields and test the approach on superimposed nondiffracting higher-order Bessel ...

Orbital angular momentum of polarization distributions of light
Journal of OpticsAbstract We investigate a new quantity for describing vector light fields with polarization singularities. Similar to the polarization singularity index (PSI), it describes the average angular velocity of the changing polarization direction.
