Yeah, but it's so fake! The light doesn't even reflect when it hits the shiny floor (lol). It would look much better if it did :.

Hehe.. i reckon they could have easily edited the reflections in too, but that would make the whole system seem even more pointless (even to the audience at large), and make it hard to find paths to render moving beams that don't hit the actors.

Then again hollywood and lasers are a bad combo - unless you dont care about the realism at all.

Halve the number of lasers...
I guess I'm stuck in the real world

Why would you use visible lasers in anyway? especially blue Why didn't they just used yellow? or something even more expensive, like argon ;D

Doesn't there have to be some sort of receiving sensor that must be hit by the beam so that it can alert if the beam is broken by an intruder? Otherwise what good do the lasers do?

Look really cool and happen to be just the right set up for a villain/protagonist to dance around?

Come on, you can't seriously tell me that's not your number 1 priority when designing a laser security system.

Real entry detection systems that work with lasers or light beams from focussed LEDs require a detector at the other end (or retroreflector at one, and laser plus detector at the other). In reality it would be very easy to set up a system that guards a door or hallway by running a couple of beams to sensors - if the beams run paralel and perhaps 6 inches apart there is no way to dance around it.

I've heard that open ended system are sometimes used by ufo hunters and such, the idea being that you can see a scanning beam hitting an object in the air. This obviously relies on scattered light from the beam, but could work given good software to detect beam interruption.

But most museums have roofs over the artwork. (I don't remember - it was a museum they were in, right?) Also, PRACTICAL laser detectors are IR.

They could have just went behind the statues but, it would look really cool

Not necessarily.

DUH

I think pointing lasers at UFOs should be illegal after what happened at Roswell Poor aliens....

Thats probably a matter of reducing cost more than anything else. If a detection system is set up properly there should be no objection to the beams being visible - you couldn't squeeze yourself trough a 6" gap even if you could see exactly where it was.

Hehe.. i guess pointing a laser beam at an alien craft doest look like the warmest welcome
On the bright side they might return fire proving existance once and for all

 

[VillageIdiot]

Plasma > lasers ;D, we don't want alien dudes pwning our tiny planet.

But if it means we know they exist, why the hell not.

 

[Pinged]

Don't worry about it. The military has all the wreckage from Roswell and they have adapted the technology for their own uses. If those alien freaks try to attack America we will kill them with their own technology.

As far as everyone else goes, your screwed.............

why not one 23009MW cyan laser that can cut right thru the dancing actor

It wouldn't have to cut him in half - just a specular reflection from a visible laser of that power would blind him! Or they could have a 20Kw CO2 laser - then the dance would be cut short, very short, or maybe a plasma cutter beam like in the first Resident Evil.
