Those are interference filters used for passive 3D (cinema) projection, such as those used by the Dolby 3D system, or those invented and produced by INFITEC®.

They're just crossed polarizers (and depend on a screen that preserves polarization).

No, they are interference filters and their use does not depend on the type of screen.

The only "interference filter 3D" I know of is this , and it isn't a filter in front of a projector but basically notch filters to distinguish two different bands within each of R, G, and B. I suppose they could be used in front of a projector, but with major light loss. Honestly, it would make a lot more sense to just do LED lights, since they have naturally very narrow emission bands.

Anyway, on capture they don't help much because of the ambiguity of separating-out 6 color channels using a 3-color CFA on the sensor....
