What is the effect of the small beam of the laser pointer?
How can the small beam of the high powered laser cause harm to the aircraft in high-speed operation? In fact, the high-power laser will spread after long-distance exposure, and even form a beam of light, making the pilots unable to see the instruments and the runway visually. In severe cases, the pilots will lose sight temporarily and even permanently damage their eyes. China currently ranks fourth in terms of damage to lasers. The output power is less than 0.4 mW, two between 0.4 mW and 1 mW, three between 1-500 mW, and four or more 500 mW. When the output power is greater than 0.4 mW, direct eye contact cannot be made. If the output power is three, it is easy to cause damage to human eyes, and the power will cause blindness.

Application
The plane flying from Qingdao to Dalian at an altitude of 3100, shoots out from the ground as a bright green light beam. When the light beam scans the eyes, the plane of the body is constantly moving, and vision and vision are immediately disturbed by stimuli and visual disturbances. Minute, the scene is a recently experienced reporter. The reporter learned during the investigation that the 200mw high-power laser pointer has been disseminated without supervision. More and more people use it as a toy, and even irradiate passers-by on the plane flying at high altitude.
