The Brownian motion of particles close to the interface between air and liquid is investigated using the one-shot
measurement of temporal autocorrelation functions as a function of the distance from the interface by using a spectraldomain
low-coherence dynamic light scattering. The technique is based on the principle of spectral-domain optical
coherence tomography combined with that of dynamic light scattering. It is experimentally found that Brownian motion
is suppressed in the region close to the air-liquid interface, but increases consistently with distance from the liquid
surface, until free Brownian motion occurs. The results confirm the potential of the proposed technique for metrological
applications.
