Fresnel-lens array proposed to make drone airframe optically transparent against sky

Published 1 July 2026

A Russian defence blogger describes a camouflage concept in which flat Fresnel lenses are tiled across a drone’s frame. The array refracts background sky light so an observer sees a continuous sky image rather than the drone body; thin frame members and motors effectively vanish against cloud cover. The flat, lightweight, rectangular form factor suits both fixed-wing and multirotor platforms. The designer notes the central mounting axis remains faintly visible, representing the principal limitation of the approach.
