The possibility to find other transformation matrices is explored. A complete set of unitary operators (R) is found to be closely related with the MJ matrices and with the evolution of pure states on the Poincaré sphere surface. We propose an alternative deduction for the condensed representation of the MJ matrices, obtained by using the Kronecker product operation and use of R unitary matrices as a tool to combine different Mueller matrices and changes of polarized states on the Poincarè sphere surface. Finally, it is shown explicitly that the columns of the transformation matrices are the eigenvectors of the MJ matrix associated to a non-depolarizing optical system and a corollary is established as a criterion to differentiate a Mueller matrix from an MJ matrix.engTransformation matrices for the Mueller–Jones formalismjournal articlehttp://dx.doi.org/10.1016/j.ijleo.2007.03.008http://www.sciencedirect.comopen access535ScatteringDepolarizationSurfacesElementsÓptica (Física)2209.19 Óptica Física
