You're crazier than a bedbug. Hope you have a good source of slightly used
retinas. Bob Gardner "Happy Dog" wrote in message . .. Hello FBI surveillance software? Anyway, I am now in possession of one brand new "Jasper" DPSS 5mw laser from bigha.com. That's the same laser used in the recent media hyped incidents at KTEB. I'm going to test the claims that pilots can be visually impaired empirically. (Guess who the pilot is.) The weather is perfect for his. -20 and clear. I plan to try it at distance of about 3500' which is as close as anyone is likely to get to a landing plane. I happen to work near a perfect stretch of parking lot (one of the best places in a busy metropolis to land if you really have to) which is perfect for this. It's very runway-like. I'm going to do three things: 1. Measure the size of the beam at a measured distance. 2. Look into the beam for about 500ms after conditioning my eyes to usual night flying light levels. 3. Have a skilled pistol marksman (cop friend) try to accurately hold the beam steady at a measured distance both free hand and with support and see what the wiggle area is. If anyone else can think of anything else they'd like to see tried (no, not in *my* plane) please post it here. This isn't meant to be a scientific experiment or to become information used instead of any government research or guidelines. OK? moo |

Hope you have a good source of slightly used retinas. There's no risk. I'm calculating safety margins for exposure with the assumption that the unit produces double its rated power. It'll still be bright though. moo |

Have fun. You'll see a fairly bright green flash, or halo, depending on
the aiming accuracy. Even with a 100 mW output, at 3500 feet any diode laser output will have expanded to many feet in diameter. You do the math. Retinal input will be on the order of 1 microwatt, assuming a 2 foot diameter beam at the reception distance. This entire laser blinding scam is a load of hogwash. My HP35 calculator had my initials burned into it's case with a 5 WATT argon laser about 30 years ago. You could put your hand into the beam at the output of the 1 meter long tube for several seconds before feeling any heat. Would I look into the beam? Hell no. Would I look into the beam of a 100 mW diode laser 3500 feet away? Hell yes. For as long as you'd like. $10 a minute. Of course, if I was a United pilot, I'd be looking for any way to recoup my pension...help, help, I've been shot in the eye by a laser!!! Pay me, pay me! And if I was a media weasel, I wouldn't even need an excuse to make up a story like this one.
