Jones Matrix Imaging for Transparent and Anisotropic Sample
Theory of Jones Matrix: The plane wave components of the optical field can be written as: According to Jones matrix formalism, E’x =Jxx Ex +Jxy Ey E’y =Jyx Ex +Jyy Ey For example the linear polarizer is characterized by the relation: 0 ≤ Px,y ≤ 1
