We present a theoretical analysis of a noncollinear polarization-spectroscopy (PS) scheme, taking into account the polarization incoherence of an arbitrarily polarized pump beam. It is based on a light-induced anisotropy (LIA) tensor formalism. Our most important results are analytical expressions for the LIA tensor, which permit classification of the nonlinear medium with LIA in terms of the polarization properties. An expression is derived for the dependence of the PS-signal intensity on the beam-crossing angle, and the usefulness of that expression for spectroscopic purposes is demonstrated.
