The laser pointer available for the blind person
Laser and optical fiber interact. The peak output of the laser is very high, reaching hundreds of thousands of megawatts. Because of its high energy, it can be used in laser cutting, laser therapy and laser weapons. In addition, laser applications include laser designator ranging, laser gyroscopes and laser processing. The simplest application of green laser pointer medicine is filling a tooth, but I don't think any patient wants to hear the sound of a drill cutting their teeth at the same time. However, when a laser pointer is used to treat teeth, there is no sound when the laser is used to cut the tartar surface or remove cavities. With laser processing, the laser can be precisely processed, even fine hair. Many processing plants require high precision, high speed and high efficiency. In addition, 500 million yen is included in the budget for 2009 to continue research on drones that stop using electromagnetic waves called microwaves. Microwave equipment, which is difficult to miniaturize, is expected to be installed on ships.

Japan is often hit by earthquakes, typhoons and other disasters. When the scale of these disasters is large, houses collapse. It is difficult to find people crushed by collapsed houses. Without water and food for a long time, people can be killed. At this point, if you have a high powered laser, it can shine through the gap, attracting the eyes of others and saving them. Lasers can also save our lives in case of fire. In case of fire, you can choose to escape to the exit or stay in a safe place and wait for rescue. Normally, a fire produces a lot of smoke and the air outlet is blocked by the fire. We can only wait for rescue. Firefighters had poor visibility because of the smoke, making it difficult to find victims. Use a laser pointer. The laser is so penetrating and bright that firefighters notice it immediately. Because drones are so cheap, there are concerns that they could be misused by terrorists. In fact, in August 2018, a drone carrying explosives was used to assassinate President Maduro in Venezuela. In September 2019, an oil field facility in Saudi Arabia was extensively damaged by a drone strike.
