crowd scanning in the USA

[buffo]

Im thinking about tearing the chauvet unit apart for the diode and using that for crowd scanning, put it in next to standard rgb.
what do you guys think about doing that?

I think you are being reckless. You have no business doing commercial laser shows.

You don't crowd-scan unless you've got both the variance to allow it *and* the equipment to verify your audience's exposure. (Not to mention the knowledge about how to to it safely.) You have none of the above.

i think that im in the middle of building a 1 watt rgb and when im done im never gonna scan anyone thats not a laserist, ever, even with a variance and CDRH approval. I was scanned at a show and HATED IT!!.

I agree !! I dont believe in crowd scanning , ( CALL ME RELIGIOUS ) even when I had a 12 mw hene with the Redline Beamscann system and that was 14 years ago.

I am glad to hear some of you guys agree.... I thought I was some sort of outcast laserist since crowd scanning didn't apeal to me. Even knowing the MPE numbers...
People are so familiar with laser after all the press they have been getting... Even where crowd scanning is legal... an audience may get skittish if they start getting hit in the eyes with lasers.

ok, this is not a dig or an attack but you just reminded me of one of my other peeves about common speech...

"I don't believe in _ _ _ _ _ _."

if you fill in the blank with something not factually proven or intangible like ghosts, unicorns and God, then thats OK. Saying "i don't believe in abortion" is silly. We all know that abortion is real. the more proper thing to say is "I'm against abortion" or "I believe that abortion is wrong" (BTW abortion is just an example please lets not go there).

Crowd scanning == pain in the eye

every cannon is loose, untill the operator learns to tie it down. By questioning the limits I learn boundaries.
by exploring possibilities I learn how to find the path to success.

every beam is diffuse before it is focused.

Don't get mad at me, get informative.

Crowd scanning can be a spiritual experience and totally immersive if done properly, that's why its so popular in Europe. Perhaps the person who scanned you had the laser above the comfort zone.

Most people would ask what those boundaries are *before* placing the public at risk though.

I'll admit that your cavalier attitude did make me angry. You want informative? OK, but I want something from you first. Make a public comittment right now to stop performing commercial laser shows until you get a proper variance.

Then search through the forums here and read up on the CDRH and laser safety. Once you have a feel for the issue, start asking questions about laser safety. I'm sure you'll get plenty of answers.

Even if crowd scanning was not hard to do legally, I probably wouldn't do it.

People win lawsuits against giant corporations after spilling hot coffee on themselves from a container that says "Caution: Contents May Be Hot!"

Imagine what that type of person could accomplish against a laser company who hasn't covered ALL of their bases before deciding to point a laser toward a bunch of people who have no way of averting their eyes quick enough to opt out of the laser radiation you're providing them with at any given time.

Steve's point about MPE levels accounting for "accidental" exposure is a really good one to keep in mind also.

While we're on the topic of involuntary exposure to light, how about involuntary exposure to sound? Few things piss me off more than a sound system that's EQed all wrong, putting out 1,000,000 decibels of treble, making my ears ring within two minutes. (I wear ear plugs, but they're rarely provided, although they should be)
I was at a show a few weeks ago (Pendulum live, Portland, OR) where this exact scenario occurred. Fortunately, I had a bunch of earplugs in my van. I literally couldn't stand the sound; it was violent!

I feel your pain.
I dislike people who invert equalizer curves and make them high at the ends and low in the middle. It was not ment to be that way. It seems to be a popular mistake and its painful.
