Protecting pilots from laser attacks! Learn about the innovative glass developed by University of Lewis scientists that can block up to 95% of red, blue, and green laser beams. This groundbreaking technology, presented at the American Chemical Society (ACS) meeting, uses liquid crystals (MBBA) to neutralize laser threats to aircraft. Discover how this automated system, triggered by a photoreceptor, can enhance pilot safety and prevent temporary or permanent visual damage caused by laser strikes. Find out how this solution addresses the growing problem of laser attacks on aircraft reported by the FAA. #LaserSafety #PilotProtection #AviationTechnology #LiquidCrystals #FAASafety #AircraftSecurity #UniversityOfLewis #AmericanChemicalSociety #LaserAttacks #PilotSafety

00:00in 2017 the federal aviation administration reported a staggering 6754 laser attacks on
00:11aircraft these dangerous acts more than mere hooliganism can blind pilots with bright flashes
00:18causing temporary or even permanent visual damage depending on the lasers properties
00:24however there's hope on the horizon scientists at the university of lewis have developed a
00:31groundbreaking glass that could neutralize this threat presented at the american chemical society
00:37acs spring meeting this innovative material utilizes liquid crystals substances with unique
00:44properties between liquids and solid crystals commonly found in electronic screens the
00:50researchers employed a solution of liquid crystals called n-4-metoxybenzene-4-butylinolen
00:57mbba sandwiched between two glass panels mbba possesses both a transparent liquid phase and
01:05an opaque crystalline phase that scatters light by applying voltage the crystals align with the
01:12electric field transitioning to their strongest crystalline state and blocking up to 95 percent
01:18of red blue and green laser beams the beauty of this system lies in its potential for automation
01:25a photoreceptor in the aircraft detects laser light triggering the energy system to apply the voltage
01:32once the laser thread is neutralized the system deactivates and the liquid crystals revert to their
01:38transparent state importantly this effect is localized ensuring the rest of the windshield remains clear
01:46this targeted approach promises to significantly enhance pilots safety and potentially eliminate the dangers posed
01:54by laser attacks
