WebAbstract. We introduce dynamic light scattering imaging (DLSI) to enable the wide-field measurement of the speckle temporal intensity autocorrelation function. DLSI uses the full temporal sampling of speckle fluctuations and a comprehensive model to identify the dynamic scattering regime and obtain a quantitative image of the scatterer dynamics. WebDynamic light scattering (DLS), also known as photon correlation spectroscopy (PCS), is a very powerful tool for studying the diffusion behaviour of macromolecules in solution. The …
WebThe diffusion coefficient is obtained from the relation Γ=D t q 2 where q is the scattering vector, given by q= (4πn/λ)sin (θ/2). The refractive index of the liquid is n. The wavelength of the laser light is λ, and scattering angle, θ. Inserting D t into the Stokes-Einstein equation above and solving for particle size is the final step. WebDynamic light scattering (also known as photon correlation spectroscopy or quasi-elastic light scattering) is a technique which can be used to determine the size-distribution profile of small particles in suspension. The size range of analysis ranges from a few nanometers to a few micrometers. These measurements can be done on suspensions …

WebDynamic light scattering enables the analysis of particles in a size range from 0.3 nm to 10000 nm. While Laser Diffraction (LD) often reaches its limits for particles smaller than 100 nm due to the weak signal and the low angular variance in scattering signal, this is where the strength of dynamic light scattering lies.
