OK Gary, I confess - polarisation of light was the subject of my final
two-year project at university many years ago. This included
photographic as well as scientific applications of polarimetry and
birefringence - including a complete theoretical analysis of the
polarisation of light through various media and at metal, dielectric and
semiconductor interfaces. The difference between circular, elliptical
and linear polarisation is only a small part of the topic. Without
exagerating, I would guess I have forgotten more about the subject in
the intervening 20 years than most people ever knew.
