Question about collimated display systems.

[Matt Olieman]

I would think 2 projectors would be stretching it, BUT, who knows, you guys just worked out a miracle. LOL

This picture might make it a little clearer on how the collimated screen works for multi projectors. I have been working on this subject with my wife for a very long time and I will try to contribute to this thread.

Great news and a big congratulations for all the great work and success you have achieved. I am very interested in anything to do with improving visuals, as I have just re-arranged the Airbus and the 3 projectors with a little better resolution and FOV. I am now using 180 degrees on nthe Triplehead with FSX. I have had to back off quite a bit on the graphics as one would expect, using that sort of screen size (3x1280x720), but it is working very well. Can even use YMML from Orbx, but need to taxi at a reasonable pace !!

Keep up the great work...............Brian W.

Hi,

This is a wonderful step in the developement of the perfect home simulator. Now don't shoot me down in flames here, but while the Milar is in the stretched form, is it possible to spray the rear surface with some type of product (Who Knows What) to make the shape permanent. Is there anyway this could be layed on it's back and filled with a product such as foam to form a permanent mould to which could be sprayed with a refective product (Who Know What). These are just thoughts buzzing through my head and feel, as silly as they sound, there might just be something that is useful for further progress.

Kind Regards

Bernie.

Actually, yes.

US patent #3,549,803 describes making a curved mirror by coating the back of a Mylar mirror with multiple layers of urethane foam and fiber glass.

Hi Mike,

Does this mean that it can't be done by a hobbyist?

Kind Regards

That particular patent was issued December, 1970. I'd be surprised if it were still in force. You can check it out at http://www.google.com/patents/about?...J&dq=3,549,803

The trick is, how do you apply the foam & fiberglass while the mirror is under vacuum?

Well, this has been onmy mind too. All i could come up with is to make a negative mould. then you could create as many mirrors as you want. So, you turn on the vaccum, then apply whatever you want to the outside, and then, when you take this shape away, you will have a master mould, and you can then make the mirror from that. Its the same process as making resin moulds from silicon, only on a much larger scale!

Let me know what you think

The trick is that you don't. You flip things over so you can pressurize the Mylar from the reflective side. It means building a totally different frame for holding the Mylar.
