Teachers of America, beware! You
a little ignorance and an unfortunately unfunny comment here. As a former military pilot and a LASER Systems Safety Officer, I can tell you that your easily acquired class 3A green laser pointer doesn’t give someone flash blindness from an accidental sweep. And the only reason that technically a class 3A laser (power output below 5mW) is considered “eye-safe” is because it produces visible light energy and the eye will typically blink before retinal damage can take place. That does not mean that it can’t blind you temporarily or that it can’t cause retinal damage…ie, if your nervous response is delayed or if you are focused intently on an ocular target and therefore have a slower blink response.
Simply based on the technical merits of how a laser operates, and specifically a class 3A green light laser operating around 532nm transmits energy and how the human retina receives/absorbs light energy, this guy had to have been deliberate about illuminating an aircraft…even if for a prank or to see if he could, a very immature and negligent thing to do.
Thank you for the info. http://www.bignews.com
