Description
Ruiyi Shen and co-authors propose a way to sense clear-air turbulence with terahertz beams in a 2026 paper. Clear-air turbulence endangers flights yet evades weather radar. Optical sensors fail in severe cases and suffer when beams drift out of line. Their beams carry orbital angular momentum, a twist in the wavefront.
Turbulence scrambles the twist modes in a pattern tied to air structure. A derived model maps that crosstalk to a standard turbulence strength measure. Lab tests and simulations confirm the link. The method stays sound where optical tools saturate and shrugs off misalignment far better. It can also locate the main turbulent clusters.
