Abstract
This disclosure teaches materials, optical targets, and manufacturing methods for making small UAS/drones highly salient in avian visual bands without materially changing human-visible appearance or flight performance. The approach uses (i) passive UV-reflective/absorptive coatings and/or (ii) UV-active bulk additives in polymer parts (e.g., propeller guards, nacelles, arms, fairings). Target spectral response is maximized in UVA 320–400 nm (with emphasis at ~350–380 nm) where most birds possess UV-sensitive cones, while maintaining low ΔE*ab (<1–2) in the human visible band (400–700 nm). The disclosure includes optical design targets, example formulations (nano-TiO₂/ZnO dispersions; dielectric stacks), integration paths (spray/dip/film/PVD and injection-mold masterbatch), mechanical and environmental durability requirements, sensor-compatibility constraints, and validation protocols (spectral, wind-tunnel, and ethological flight trials).
