Determination Of The Electric Cross-Spectral Density Matrix Of A Random Electromagnetic Beam
It has been shown in a recent publication that in order to calculate the changes which the degree of polarization, the degree of coherence and the spectrum of a random electromagnetic beam undergo as the beam propagates, it is necessary to know the 2 × 2 cross-spectral density matrix of the fluctuating electric field. In this paper, a procedure is described for measuring the four elements of this matrix, with the help of two polarizers and a rotator. The procedure makes use of the Young interference experiment and the recently derived spectral interference law for such beams. © 2003 Elsevier B.V. All rights reserved.
