We present a general theory of spin-to-orbital angular momentum (AM) conversion of light in
focusing, scattering, and imaging optical systems. Our theory employs universal geometric
transformations of non-paraxial optical fields in such systems and allows for direct
calculation and comparison of the AM conversion efficiency in different physical settings.
Observations of the AM conversions using local intensity distributions and far-field
polarimetric measurements are discussed.
