         Dear
          Dr. L********,  Please
          feel free to include it in your lecture.  A
          rigorous mathematical proof of scalar interferometry is given by M.W.
          Evans, "O(3) Electrodynamics," in vol. 2 of Modern Nonlinear
          Optics, Second Edition, 3-vols., edited by M.W. Evans, Wiley, 2001,
          Vol. 2, p. 79-267. This 3-volume set is vol. 119 of Advances in
          Chemical Physics, Series Editors I. Prigogine and Stuart A. Rice. 
           The section of interest is Section X, beginning on p.
          172.    Another
          rigorous scalar interferometry mathematical treatment is given by M.W.
          Evans et al., "On
          Whittaker's Representation of the Electromagnetic Entity in Vacuo,
          Part V: The Production of Transverse Fields and Energy by Scalar
          Interferometry," Journal of New Energy, 4(3), Special
          Issue, Winter 1999, p. 76-78.  Best
          wishes,  Tom
