F. Ratajczyk, DETERMINATION OF BOTH THE STATE AND THE DEGREE OF POLARIZATION FOR A MIXTURE OF NONUNIFORM, INCOHERENT-LIGHT BEAMS WITH THE AID OF POINCARESPHERE, Optica Applicata, 25(2), 1995, pp. 103-107
It is assumed that the total light beam is composed of two (or more) m
utually overlapping incoherent beams of light which are partially pola
rized being all in different states of polarization. The resultant sta
te and degree of polarization for the sum of these beams may be determ
ined with the aid of Poincare sphere. In this paper, the ''mixing'' ru
les for polarization states have been formulated for the case of incoh
erent beams.
