@Andrew – I spoke to one of the chief engineers for IMAX 3D regarding the shutter glasses and was surprised what he said – essentially (at the time) they proceeded with linear polarization because they were unable to produce a shutter-glass system that could withstand a wash cycle in a dishwasher (how they intended to clear them between viewings).

Xpand has done well especially in Europe in the last 1.5 yours.
They have now also introduced coded glasses.. Ie, so you cannot steal them and use them at home on the new 3D TVs coming out.

But this does bring to light, that once active glasses are main stream and china makes them for cheap, it will make Cinema 3D also much more affordable for the exhibitor.

but it looks like there are still many listed on the XpanD site:

Again, very nice work. It is great to see the 3D systems actually in action. Keep up the good work!
One small correction, IMAX did use shutter glasses in the past for their 3D installations, however my understanding is that over the last few years they have almost completely transitioned to using only linear polarised 3D in their theatres. This applies to both the film based IMAX 15/70 theatres and also the newer IMAX digital systems. I am not aware of any IMAX 3D theatres still using the original IMAX shutter glasses, but I’d be happy to be proven wrong.
