Stabilizing Turbulent Laser Beams with Electric Dipoles
Researchers from the Indian Institute of Space Science and Technology (IISST) have developed a novel method to combat atmospheric turbulence effects on laser communication beams.
A team of researchers used polymethyl methacrylate (PMMA), a common plastic, to partially correct a distorted laser beam and restore its statistical order.
Their approach combined physics with a statistical framework based on geometry to stabilize a beam of light, moving towards more reliable high-speed internet.
A novel scheme to control drones can enable complex formation flying using only camera data, without GPS or inter-drone communication.
The research was published on the preprint server arXiv and is yet to be peer reviewed.
