Real-time detection of airborne asbestos by light scattering from magnetically re-aligned fibers
(2013-05)
Inadvertent inhalation of asbestos fibers and the subsequent development of incurable cancers is a leading cause of work-related deaths worldwide. Currently, there is no real-time in situ method for detecting airborne ...
Incidence of rough and irregular atmospheric ice particles from Small Ice Detector 3 measurements
(2013)
The knowledge of properties of ice crystals such as size, shape, concavity and roughness is critical in the context of radiative properties of ice and mixed phase clouds. Limitations of current cloud probes to measure these ...
Retrieving the size of particles with rough and complex surfaces from two-dimensional scattering patterns
(2012-12)
Scattered intensity measurement is a commonly used method for determining the size of small particles. However, it requires calibration and is subject to errors due to changes in incident irradiance or detector sensitivity. ...
Retrieving the size of particles with rough surfaces from 2D scattering patterns
(2011)
Scattered intensity measurement is a commonly used method for determining the size of small particles. However, it requires calibration and is subject to errors due to changes in incident irradiance or detector sensitivity. ...
Light scattering by ice particles in the Earth's atmosphere and related laboratory measurements
(University of Helsinki, 2010)
The microphysical properties of ice crystals, such as size, shape, concavity and roughness, are important in the context of radiative properties of ice and mixed phase clouds. Limitations of current cloud probes to measure ...
Classifying atmospheric ice crystals by spatial light scattering
(2008)
We describe preliminary results from an optical scattering instrument designed to assess the shapes and sizes of microscopic atmospheric cloud particles, especially the smallest ice crystals, that can profoundly affect ...
Laser diffractometer for single particle scattering measurements
(2002)
A laser diffractometer (polar nephelometer) constructed for single-particle studies is described. It takes advantage of an array of optical fibres and a scanning disc to allow the use of a single photomultiplier tube for ...
