This is also for research purposes. Do they signal an alarm? How do laser lights work and how to get past them? (I believe that high technology would be categorized under other-science?)

as for whether lasers burn or hurt, it depends on what wavelength (color, may be invisible to the eye) the laser is, and the power intensity of the laser. For example, there are lasers used as precision surgical cutting tools, and there are lasers used as classroom pointers.

as for laser alarm systems as seen in movies (bank/museum vaults), typically the laser is shining on a receptor. If the laserbeam is blocked, the receptor is no longer seeing the laser, so the receptor triggers the alarm.

There was a recent Mythbusters episode on that. I think they found that lasers aren't even used all that much anymore, too many issues. I believe infrared is becoming the more popular choice?

I think all these alarms work the same way. You have a connection from one wall to the other, and the circuit remains intact while the sensor connect. As soon as something INTERRUPTS them, and breaks the circuit, the alarm goes off.

I don't believe a laser used for the purpose of a sensor would burn or injure you... I think it's use is to form a difficult sensor for people to avoid. I would think more people are interested in the arrest of an individual attempting to break in... then burning or killing them...

The lasers used in booby traps don’t do either. They would be used with a photo sensor to detect a break in the path of light and that would trigger another event. A laser with a high enough power to harm a human would give them a burn. The severity of the burn would depend on the power of the laser and if were focused or not.

the ones in real life are shining on a photo-electric sensor and when the beam is 'broken' they trigger the sensor that triggers the device ( alarm or other ) NOW IN THE MOVIES they do just about anything !!!! the movie trick with the mirror ( reflecting ) implies that they reflect back on themselves like a laser speed gun -way to expensive and complicated for real life AND they are used in alarm systems to cross large openings ( like rooms ) in most cases the light beam is not a LASER just a beam of infrared light doubtful they are used in anything you would call a booby trap anywhere in reality

The only lasar tech-toy I know of is the one used in a thermometer. Alarms seem to be passive UV systems.

They won't give you a shock unless they're huge! They can damage your eyes!

Goggle it!

What's a bobby-trap? Is that like when you "fire at Will"?

I'm not that brainy to know that. Why don't you experiment?
