Kind of, but not true. So this concept is real. It is usually done with an invisible (infrared) laser pointer. Your garage door may have someone who can stop the door from closing. These systems (called active infrared) can also be used for alarms. However, there is absolutely no reason for a large group of people to meander in the corridor. If you want to cover the lobby (instead of just using the laser to cover the entry point) or other larger areas. It makes more sense to use a motion detector (passive infrared).
Unfortunately, this is not good for Hollywood. Because defeating the PIR requires moving very slowly (if you are bored and want to try a laser pointer. Please test on the automatic door of the grocery store and try to move all the way up to the door without triggering the sensor) and then open the door). The cool ninja flip is the exact opposite of what you need to do. You will not get such a scene. As long as this view continues, I can put my doubts aside. Interestingly, both AIR and PIR devices have been used as laser pointer triggers for improvised explosive devices (IED).
What happens if a person is shot by the US Navy's LaWS (Laser Pointer Weapon System)? My policy is not to describe the damage to the human body in detail, because some people will find it interesting. This will lead to major events, potential international incidents, career destruction, numerous reports, investigations, designated scapegoats, new rules of engagement, etc. I have always compared high-energy laser beams with direct exhaust from jet engines and afterburners.
