Pre-test experiment of laser pointer on aircraft
"Exposure to Laser pointer radiation-investigation of exposure to pilots and drivers of public transportation during work", due to the steady increase in the number of laser pointer attacks, FH Munster (LFM) determined the potential hazards and evaluated the research work taken Possible preventive measures. For this reason, the beam characteristics are pointers from more than 40 different wavelength ranges from Far East Online providers from 405 nm to 655 nm ("blue", "green", "red"), and the power is up to 1000 mW in terms of measurement technology. . Facts have proved that the specified laser power is exceeded in almost all cases; in extreme cases it can even be as high as 20 times! Further research has shown that the laser pointer radiation has a high degree of polarization of up to 99% and has a “hot spot” with blue and red radiation characteristics in a strongly non-uniform area, with a clear intensity distribution.

Laser pointer hazards-investigation of hazards for pilots and public pilots. Due to the increase in laser pointer attacks, we focus on potential dangers and evaluate possible preventive measures. This is a selection of 40 laser pointers from a Far East supplier from 405 nm to 655 nm ("blue", "green", "red") and output power up to 1000 mW. It is shown that in most cases, the specified output power is significantly more than> 20 times. Further studies have shown that the radiation from the laser pointer shows a strong polarization of up to 99%. It can also be seen that in the case of blue and red laser pointer radiation, characteristic "hot spots" appear in the intensity distribution. The developed theoretical model not only considers the beam parameters, but also considers air absorption and reduction of transmission from the windshield of airplanes/helicopters and vehicles. The results show that in the range of hundreds of meters, the commercially available laser pointer is used. Even at a few thousand meters, glare effects may still appear.
