Question about collimated display systems.

[Matt Olieman]

This is a 180 degree system (a very old one). This system has 4 projectors and the projectors are out of the sim or rear display compartment. Projecting at a angle downwards. The 5 projector system I mentioned earlier was similar to this one, except it was level D.

How curved glass is made:

@Jordan - any mold has to have a surface that is mirror-perfect. That's, really, really hard to do.
Commercial flight simulators use thin film mirrors because they're very light and compared to the same size in glass, dirt cheap to make.

@Matt - was that sim built that way or was it on a motion base at one time? I've never seen a static sim with a collimated display and no base. It's weird.

@Mike - Smart aleck.

I don't recall this particular one....

I used to travel quite a bit (cross country), I'd try to hit every Flight Sim School there was. I do remember seeing static sims with a collimated display.

What about if not sucking air out from backside of mylar, but pushing air in front side.
I think it will make same thing to mylar and you can add something urethane foam etc to backside.

I believe the patent Mike Powell mentioned specifically states that the first layer should be some sort of uniform material (a few coats of plasticized primer should do), as the voids in foam result in an imperfect surface. Otherwise, you've got the idea.

What about applying the material to the rear surface while not being stretched and then using the stretching process to pull it into shape giving the first layer time to set.

Mylar takes a lot of force to get it into the proper shape. I doubt a single layer on the back would hold the proper mirror shape. I think you would need to apply multiple layers and let them all cure and gain strength if the finished mirror is to be useful.

Hi Guys ..

Congratulations , this is a historical moment in our hobby !! cheers

you made a great step guys , who believed it's possible to make a DIY collimated mirror display system for our replicas !! , So we can modify & discover ways to solve the distortions in the view that appeared in the videos ..

I'm so sorry my english isn't well btw it was so tiring to translate words in your last 169 posts .. I have read all posts as i can & I have already got the general idea ... I'm trying to make a frame from wood with a vertically - horizontally FOV 40 - 180 degrees , & I'm going today to a mirror factory to ask them if they can made a mirror that can be formed on the wooden frame form .. but in all your posts you were talking about "Mylar" and you didn't talk about making the mirror at a factory or a workshop .. whatever .. is it expensive to order a mirror by the shape we want ?? or they can't do it in an accurate optical properties ??

another question .. how the vacuum form the mylar ?? please explain because i didn't get how it form the shape of it ..

Thanks for your nice thoughts & posts ..

Did you look at all the videos? Gives you a good idea how this is done and the genius of it all. It's not as simple as to ask a mirror company to build this, there's a bit more to it than just that.

Most of your questions will be answered in this thread. It's quite informative.
