# Laser-Based Jet Metrics The 'LASSI' Can Measure Jet Velocity with UV Lasers By Hayley McGlone | Published 2016-07-23 | Tech Source: Trend Hunter, https://www.trendhunter.com/trends/lassi References: [digitaltrends](http://www.digitaltrends.com/cool-tech/laser-airspeed-lassi-bae-systems/?utm_source=feedly&utm_medium=webfeeds) & [baesystems](http://www.baesystems.com/en/article/bae-systems-develops-laser-airspeed-sensor-for-aircraft) BAE Systems has developed a new system to measure jet velocity with LASSI, or Laser Air Speed Sensor Instrument. The sensor is designed for use in high altitude aircraft because of its ability to increase survivability and improve fuel efficiency and performance. LASSI operates by bouncing ultraviolet laser light off of air molecules. The sensor then measures the change in 'color' of the reflections so the further away the reflection is, the faster the aircraft is traveling. BAE Systems wants to miniaturize the technology and research how it can be integrated into aircrafts in the coming years. LASSI's ability to detect the speed of another aircraft through ultraviolet light will be an incredible feature for flight safety, especially for military jets that travel at incredible speeds. ## Trend Insights (Trend Hunter) - Score: 3.9/10 - Popularity: 49% | Activity: 59% | Freshness: 8% - Audience gender: 50% men, 50% women - Primary generations: Millennial, Gen X - Top markets: North America ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Tech](https://www.trendhunter.com/tech) > [Gadgets](https://www.trendhunter.com/gadgets) ## Key Themes ### What Makes This Trend Stand Out - **Laser-based Air Speed Sensor Technology:** BAE Systems' LASSI technology has the potential to revolutionize air speed measurements for high altitude aircraft. - **Miniaturization of Jet Metrics Sensors:** The miniaturization of LASSI technology could lead to its integration into a variety of aircraft in the future. - **Ultraviolet Light Detection for Flight Safety:** LASSI's ability to detect jet speed through ultraviolet light has significant implications for flight safety in military jets. ### Sectors Adopting This - **Aviation:** BAE Systems' LASSI technology has direct implications for the aviation industry, especially for high altitude and military aviation. - **Military:** LASSI's potential for increasing flight safety for military jets highlights its direct industry application. - **Sensor Technology:** The development of LASSI technology demonstrates the potential for continued innovation and advancement in the world of sensor technology. ## Related on Trend Hunter - [Groundbreaking Thermal Conductivity Systems](https://www.trendhunter.com/trends/thermal-conductivity.md) - [Digital Measuring Tools](https://www.trendhunter.com/trends/lidar.md) - [Laser-Controlled Military Drones](https://www.trendhunter.com/trends/lasercontrolled-military-drone.md) - [Laser-Powered Coding Systems](https://www.trendhunter.com/trends/videojet-7920-uv-laser-marking-system.md) - [Heavy-Duty Hybrid Drones](https://www.trendhunter.com/trends/hybrid-drones.md) - [Futuristic Missile Interceptors](https://www.trendhunter.com/trends/missile-interceptor.md) - [Electro-Optical Intelligent-Sensing Systems](https://www.trendhunter.com/trends/electrooptical-intelligentsensing-systems.md) - [Smart City Infrastructure Tech](https://www.trendhunter.com/trends/siliconphotonics.md) - [Aerial Fertilizer Measuring Tools](https://www.trendhunter.com/trends/asd-fieldspec-4.md)
