Time-varying coherency matrices and spectral coherency matrices

Abstract

The problem of spectral analyses, in terms of optical observables, of the time-varying spinorial fields encountered in optics is presented. Time-varying coherency matrices and spectral coherency matrices are introduced. The spectral analyses of the output of a KDP electro-optical modulator is presented as an example. The paper is conceived as a contribution to the development of the language of the optics of observables.
