the major and minor axis of this ellipse are always in the x,y directions,which are exactly the fast and slow directions of a quarter of wave plate,consequently,emergent light  from a quarter of wave plate is linearly polarized light,the included angle between its polarization direction and y axis is ¿Ú¡£Hence£¬turning analyzer ¿Ú form orthogonal position can minimize the output, this angle is extinction angle,which can be detected by analyzer,birefringence gradient ¦¤R is calculated by following equation:
