Heterodyne Near-Field Scattering
Doriano Brogioli, Alberto Vailati, Marzio Giglio
We describe an optical technique based on the statistical analysis of the random intensity distribution due to the interference of the near-field scattered light with the strong tr…
A schlieren method for ultra-low angle light scattering measurements
Doriano Brogioli, Alberto Vailati, Marzio Giglio
We describe a self calibrating optical technique that allows to perform absolute measurements of scattering cross sections for the light scattered at extremely small angles. Very g…
Real-Time Wavelet-transform spectrum analyzer for the investigation of 1/f^αnoise
Doriano Brogioli, Alberto Vailati
A wavelet transform spectrum analyzer operating in real time within the frequency range 3X10^(-5) - 1.3X10^5 Hz has been implemented on a low-cost Digital Signal Processing board o…
Soret driven convection in a colloidal solution heated from above at very large solutal Rayleigh number
R. Cerbino, A. Vailati, M. Giglio
Convection in a colloidal suspension with a large negative separation ratio is studied experimentally by heating from above. Shadowgraph observation at very large solutal Rayleigh…
