Polarization-resolved exact light backscattering by an ensemble of particles in air.


We present the first experimental observation of exact backscattering of light by an ensemble of particles in ambient air. Our experimental set-up operates in the far-field single scattering approximation, covers the exact backscattering direction with accuracy (θ = π ± ε with ε = 3.5 × 10(-3) rad) and efficiently collects the particles backscattering… (More)
