Paper Abstract

In this work we derive the birefringence matrix of a twisted nematic liquid crystal using Jones matrix formalism. It is assumed that due to the shape of the molecules and negligible absorption each plane slice of a liquid crystal cell exhibits a uniform intrinsic birefringence (linear or elliptical). Under this scope, it is shown that the anisotropy of the twisted nematic liquid crystal is described by an inhomogeneous birefringence matrix. A polarimetric procedure to verify this result is also proposed.
