Paper Abstract

Variable coherence tomography (VCT) was recently developed by Baleine and Dogariu for the purposes of directly sensing the second-order statistical properties of a randomly scattering volume. In this paper we generalize the theory of VCT to include polarized inputs and scatterers. The measurement of the scattered coherency matrix or Stokes vector is not adequate in general to describe the surface, as these quantities depend on the coherence state of the incident beam. However, by controlling the polarized coherence properties of the beam with polarized VCT, we are able to design a method that can measure analogous information to the polarimetric BRDF, but do it from monostatic data. Such a method has potential impact on both polarimetric and scalar active remote sensing.
