Optical Modelling
We have three different models which we commonly use, the
Jones, the Berreman and the Grating Method.
For most applications the LC director varies slowly with respect
to the wavelength of light. The Jones method is a fast and effective
means to calculate the optical propagation through polarisers and
the LC layers. The extended Jones method is an extension to describe
oblique incidence.
If there is significant reflection between layers the Berreman should be
used instead of the Jones method. When there is a rapid lateral variation of
the director field, diffractive effects become significant. The Jones
and Berreman methods are essentially 1D methods, that don't take into
account these effects. In such cases we use a Reduced Grating Method,
which is a variation of the standard Grating Method that uses subspace
projection to reduce the order of the problem.
