| 释义 |
A laser fence or laser wall is a mechanism to detect objects passing the line of sight between the laser source and the detector.[1][2] Stronger lasers can be used to injure entities passing the laser beam.[3] In fiction, laser fences may have the ability to stop intruders by blocking or injuring them. DescriptionA laser fence mechanism detects objects passing the line of sight between a laser source and detector.[1] Stronger lasers can be used to injure entities passing the laser beam, as in a mosquito laser.[3] Fictional uses of laser fences often extend the concept so that fences may have the ability to prevent intruders by blocking or injuring them.[4][7][8][9][10] UseAgricultural usageLasers are used to keep birds from eating blueberries by being perceived as a predator.[5] The European Commission is funding research into a laser fence to scare away rats and other pests.[6][7][8] Border fencesThe Indian Border Security Force (BSF) has implemented a laser wall system—called LASER Wall—along some parts of its border to stop intrusion.[9] FictionFilmsIn the 1992 film Fortress, prisoners are kept secured by laser walls.[4] Videogames{{example farm|section|date=September 2018|reason=Dealing with this conceptually and mentioning examples would be preferred to just listing examples. Ideally, it would incorporate sources discussing the concept as a whole, rather than just examples.}}Laser walls appear frequently in videogames.[10][11][12] The concepts of these fictional fences can be compared to other concepts like tractor or repulsor beams and force fields.
