Raindrops scatter 905 nm laser pulses through Mie scattering, reducing point cloud density by up to 73% at 25 mm/h intensity—degradation that scales nonlinearly with droplet size distribution, not just rainfall rate.
Fog attenuation follows exponential decay governed by Beer-Lambert law, but standard models underestimate backscatter from polydisperse aerosols, leading to false ‘free-space’ classifications in autonomous vehicle perception stacks.
