Polarimetric description of superposing random electromagnetic fields with different spectral composition

Abstract

We present a polarimetric technique that provides a complete description of a mixture of uncorrelated optical fields with different spectral and polarization properties. The second-order coherence theory is used to describe the superposition of two random optical fields, and an imaging experiment is reported that illustrates the capability to separate radiations with different spectral composition and to simultaneously determine their Stokes vectors.
