This is a simple description. For detailed explanations see articles: Laser Diffraction-101 and -201. Particle Size Distribution (PSD) is a multi-parameter description of how the total concentration of particles is distributed into many size fractions. For example, a 32-element PSD means that the...

The LISST-SL2 is an advanced version of the original LISST-SL instrument for sediment transport studies. It is not a sampler. It draws water in and blows it out. No water sample is retained. Laser optics and electronics are contained within the streamlined body. Power and communication is via the 2-conductor...
PRELIMINARY ANNOUNCEMENT – PiA 2018 [photo of venue to come] Date: 24 – 27 September, 2018 Updated: 11 April, 2017. The First PiA Conference will be held in Vittoria, Brazil at the Universidade Federal do Espírito Santo. The initial sponsorship is by the University del Norte, Barranquilla,...
The LISST-VSF is the first autonomous VSF instrument for use in the sea. It measures the Volume Scattering Function, the beam attenuation and scattering coefficients (c and b), and depolarization via the elements P12 and P22 of the scattering Mueller matrix. NASA funded the development of the LISST‑VSF...

Sequoia’s LISST-Infinite and LISST-Hydro products generate data on sediment concentrations in water entering turbines. However, there has been no guidance for plan operators on what levels are dangerous, or at what level the operator should shut down turbines. At a conference of the IAHR in Grenoble,...
While testing a LISST-ABS in the laboratory with field samples, Dr. Benjamin van der Waal of Rhodes University in South Africa noticed an apparent instrument drift. He was using samples extracted from a river for this testing, so that the samples were likely a mixture of cohesive sediments. In a test...
The optical scattering function (VSF) describes how incident light on a volume of water is scattered into various directions. It is an important inherent optical property of water – a term used by optical oceanographers. The VSF at small forward angles is important in determining beam spread or in...
