I love that movie!

"What is it?"
"It's a laser beam, bozo!"
"What's it for?"
"Not what! WHERE!"
"What?"
"Follow it... It's a surprise!"

Which, of course, leads everyone to the "first annual tanning invitational" party. And one of the more memorable lines in the movie: "Don't eat that! Don't you know that eating that can give you very large breasts? Oh my God! I'm too late!"

Priceless...

The movie is called Real Genius. Here's the IMDB link to it.

The actors were a lot younger when they made that movie. (It came out in 1985!) Looking at the pics they have on IMDB now doesn't do the film justice. (Well, you can tell by how young Val Kilmer looks on the box.) Still, a great movie.

:shock: I forgot that was him... DAMN, I feel old now... :(

How do you get teh tunnel in a tunnel... O, I feel dumb... Make a big tunnel, then a smaller one inside it huh? :oops:

Concentric circles... The ilda file looks like a small ring inside a larger one. Nothing to it, really...

And you think you're old? That movie came out *after* I graduated from high school. We're *both* a bunch of old farts...

like so

Ah... That's right - the other projector didn't have galvos, just spinning mirrors. But yeah, setting one laser to hit the mirrors at a shallow angle while the other is aligned to a sharper angle will make the relative pattern sizes different, also giving you the circle-within-a-circle effect.

Adam

i hate to say your wrong again, but... LOL

its not a circle in a circle, there the same size just ext to each other but when i took the pic it turned out like that

Hmmm... Interesting.

I've done several experiments with the spinning mirror effect, including the two laser idea, and one of the problems I had was making sure that the path each beam took between the two mirrors was roughly equal. If the path lengths weren't equal, then one beam would draw a larger circle (off the first mirror only) than the other beam would, and the patterns would be *slightly* different. I assumed that you had the same thing going on, only on a much larger scale.

Then again, I was using a home-made rig with fairly large mirrors to begin with, and I probably had more "wobble" on the mirrors than I needed. Thinking back on it now though, the small differences I noticed were probably about as bad as they could ever get with that sort of setup.

Then too, if you have small mirrors to start with you can't hardly get them too far miss-aligned or the beam won't hit the second mirror at all. Evidently that's the arrangement you have in your projector.

Still, it is hard to tell that the circles are not concentric from the pics. It's a cool effect!

Adam

a few more pics and videos to help you all out on how i got the effect
