BAE Systems has developed a concept which it believes will help battlefield commanders enhance their ability to observe adversaries’ activities over much greater distances than existing sensors.
The Laser Developed Atmospheric Lens (LDAL) concept, developed by technologists at the Company’s military aircraft facility in Warton, Lancashire, has been evaluated by the Science and Technology Facilities Council (STFC) Rutherford Appleton Laboratory and specialist optical sensors company LumOptica and is based on known science, the company said in a statement Sunday.
The lens could be used as a form of ‘deflector shield’ to protect friendly aircraft, ships, land vehicles and troops from incoming attacks by high power laser weapons that could also become a reality in the same time period.
It works by simulating naturally occurring phenomena and temporarily - and reversibly - changes the Earth’s atmosphere into lens-like structures to magnify or change the path of electromagnetic waves such as light and radio signals.
LDAL is a concept that copies two existing effects in nature; the reflective properties of the ionosphere and desert mirages. The ionosphere occurs at a very high altitude and is a naturally occurring layer of the Earth’s atmosphere which can be reflective to radio waves – for example it results in listeners being able to tune in to radio stations that are many thousands of miles away. The radio signals bounce off the ionosphere allowing them to travel very long distances through the air and over the Earth’s surface.
The desert mirage provides the illusion of a distant lake in the hot desert. This is because the light from the blue sky is ‘bent’ or refracted by the hot air near the surface and into the vision of the person looking into the distance.
LDAL simulates both of these effects by using a high pulsed power laser system and exploiting a physics phenomena called the ‘Kerr Effect’ to temporarily ionise or heat a small region of atmosphere in a structured way. Mirrors, glass lenses, and structures like Fresnel zone plates could all be replicated using the atmosphere, allowing the physics of refraction, reflection, and diffraction to be exploited.
