Hi everyone,

A friend of mine attending university in Japan is trying to write a paper in English discussing the effect that occurs when looking at a screen through polarized sun glasses (i.e. it looks dark or black).

She is looking for a formal term that specifically addresses the screen appearing black, rather than the cross-polarization that underlies the effect. The phenomenon rather than it's mechanics.

Is there a formal term for that? Occlusion doesn't sound like it would be right, but maybe it is; I am not a scientist (only trying to help out).

"Polarisation discrimination"?
"Cancellation of cross polar component"?
But the term "Cross Polarisation" is used in the contexts of Light and RF, so what's wrong with it?

Hi sophiecentaur and e-pie,

On the basis of your feedback she's going to go with "cross-polarization effect" and "cross-polarization problem" in her paper.

Apparently they have a specific word for this in Japanese, and she was looking for a precise equivalent in English. That said, I think this will be fine.

Thank you very much for your input. I recognize this isn't exactly exciting stuff.

I have also come across the term "Cross polar rejection".
There is a range of terms and the context of a well written article will resolve any possible confusion. I would suggest that your friend reads around. Google search and then a search of each document can save time when you are after a specific word and its uses.

Extinction. I think this is the word used by researchers like Faraday.
