I'm going to "Laser" a pilot.

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?

You're crazier than a bedbug. 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.

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.

Hey Happy Dog. Why don't you get a spot on "Myth Busters". I'll fly and
you aim the laser. Then we can swap positions and show the entire world
what a load of crap this entire laser thing is.

I *hate* publicity. Knock yourslef out.

Those of us on alt.lasers are having several discussions of this same
topic. Our take is that this is a lot of nonsense, possibly with some
ulterior motive on the part of the government. One person wrote a
letter to one of the government agencies involved, and posted the
reply. The government stands by their story that a doctor (notice, one
doctor) found retinal burns on the pilots he examined (laser source
unknown). We still think it's a bunch of nonsense (several of us have
worked around a lot of lasers, and I, for one, have a degree in Laser
Electro-Optic Technology).

Are you referring to the Delta pilot in the story at the link below,
or the military pilots?

"Pilots"? More than one? Anyway, I didn't know that there was an alt.laser
so I'll xpost this to there.

How many instances of retinal damage has there been to spectators of laser
entertainment shows? I've never heard of one. Although not legal in the
US, in other countries, laser entertainment systems with output power of
over twenty watts are regularly used directly on audiences. The laser is
"scanned" using fast moving mirrors or put through various types of
diffraction optics. The levels are far lower at any given observer point.
But they're still often well over 5mW.

"Pilots"? More than one?

The letter that one of the members on the laser forum, Skywise,
received from the APSA refers to multiple pilots with retinal burns.
Here's the link to his Web page:

"Anyway, I didn't know that there was an alt.laser"

Technically, it's alt.lasers .
so I'll xpost this to there.

So I see.
