The state of polarization of light is determined by ? the relative amplitudes (Eox, Eoy) and, ? the relative phases (? = ?y ?x ) of these ponents ? The plex amplitude is written as a twoelement matrix, the Jones vector ????????????????????????? ????ioyoxiyioyioxoyoxo eEEeeEeEEEE xx~~~5 Jones vector: Horizontally polarized light ? The electric field oscillations are only along the xaxis ? The Jones vector is then written, where we have set the phase ?x = 0, for convenience ??????????????????????????????0100~~~AAeEEEExioxoyoxo?x y The arrows indicate the sense of movement as the beam approaches you The normalized form is ??????016 x y Jones vector: Vertica
