High-energy laser pointer

The high-energy, invisible blue laser pointer can cause bleeding in the fundus, blinding and uncontrollable pilots," Roider explained. Lasers with a beam diameter of more than one meter have been used along the coast of Somalia to temporarily blind pirates, making them unable to fight. Since 1995, the Geneva Convention has banned laser weapons, the main purpose of which is to cause permanent blindness. When a pilot becomes a victim of a high powered laser pointer attack, commercially available equipment can even reach an aircraft up to 15 kilometers high-it is difficult to be sure. Permanent damage to the victim’s eyes. In recent years, laser presentation software technology has made great progress. Although computer software changes every day, unfortunately such software (such as CAD) cannot be used for laser presentations. The reason is that the beam cannot be used for laser presentations. It is scanned and controlled like the electron beam in a picture tube. In addition, the scanning dots of the laser on the screen cannot emit afterglow like the phosphor screen on the picture tube. It will disappear immediately, and new computer algorithms need to be used to design the laser demonstration software. 1 Class lasers are not bright enough to be used as pointers. Therefore, laser pointers are classified as Class 2 or Class 3A. They emit up to 5 milliwatts of energy and produce exposure that damages the eyes faster than blinking. The UK has banned the sale of Class 3A laser pointers , Although they are legal in Canada and the U.S. Many states and local governments in the U.S. have issued regulations restricting the use of Class 3A pointers.
