%0 Book Section %T General classification of partially-polarized partially-coherent beams publisher SPIE--The International Society for Optical Engineering %D 2002 %U 0-8194-4727-7 %@ https://hdl.handle.net/20.500.14352/60796 %X The behaviour of the so-called generalized degree of polarization of partially-coherent partially-polarized beams upon free propagation is investigated. On the basis of this parameter a general classification scheme of partially polarized beams is proposed. The results are applied to certain classes of fields of special interest. %~
