So I saw Avatar in 3D, and we were examining the glasses afterward. I thought that the newer 3D films used polarized light, but I have two problems understanding this.
How do you put polarized light off a screen? I was told that reflected light was polarized by the reflection. Is polarized light still in the same orientation because it was polarized first?
We showed that if you put a right lens over a left lens, you get black. This didn’t change by rotating them. Other polarized films I’ve seen did.
I know on this board there’s someone who knows, and even possibly someone who did a technical paper on the method. Thanks.
