An interesting approach using two CRT projectors to display 3D ...

Anyone going to try this?
I have a 40" Samsung that will be hitting the trash. I can strip the panel down and send the filters for the cost of shipping.

Here is some Circular Screen material.

Now I need to look for clear Circular polarizer material for the lenses .

I think with Circular only one Projector would be needed right?

Here it is

But they have a section for 3d and use linear so maybe that is the best way to go?

have to look up 3d Circular Polarization

Here is an explanation I found on Circular polarization

http://www.awater3d.com/en/faq/zirkulare_polarisationsfilter/72/

Circular polarization filters work along the same principles as linear polarizers. The difference between the two is as follows: In linear polarizers the light waves are polarized such that they all oscillate within a single plain. Circular polarizers, however, align the light waves to rotate either clock-wise or counter clock-wise – comparable to the shape of a corkscrew as they move towards and from the projection screen. Analogously, the glasses worn by the spectator have the respective orientation.

The biggest advantage of circular prolarizers over linear polarizers is that even if spectators tilt their heads completely one can guarantee very good separation of channels. The 3D experience is not compromised.


Looks like they have it all under one roof !!

Screens front or rear, filters, the 210 mm should work for each CRT lens and glasses.
