Natural monochromatic light of intensity-I o falls on a system of two Polaroids between which a crystalline plate is inserted, cut parallel to its optical axis.
The plate introduces a phase difference δ between the ordinary and extraordinary rays. Demonstrate that the intensity of light transmitted through that system is equal to where ф and ф' are the angles between the optical axis of the crystal and the principal directions of the Polaroids.




In particular, consider the cases of crossed and parallel Polaroids.
