Light scattering by complex ice-analogue crystals
(2006)
Angle-dependent light scattering measurements on single ice analogues crystals are described. Phase functions and degree of linear polarization are measured for electrodynamically levitated crystals. A procedure for ...
Introducing phase tracing into a computational method which combines ray-tracing with diffraction on facets
(University of Bremen, 2005)
The viability of introducing phase tracing into our ray tracing with diffraction on facets model is investigated. In order to prove the method, Monte Carlo ray-tracing results for a slit, based on our diffraction formula ...
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 ...
Stability characteristics of cylindrical fibres in an electrodynamic balance designed for single particle investigation
(2002)
An electrodynamic balance (EDB) of the double ring double disc type has been designed for studying single microparticles. It allows electrostatic particle injection and recovery as well as alignment of elongated particles. ...
Magnetic anisotropy of asbestos fibres
(1999)
The anisotropy of magnetic susceptibility of single asbestos fibers is measured. The alignment of both chrysotile and crocidolite fibers in magnetic fields is found to be due to the anisotropy. The average measured anisotropy ...
Application of neural networks to the inverse light scattering problem for spheres
(1998)
A new approach suitable for solving inverse problems in multi-angle light scattering is presented. The method takes advantage of multidimensional function approximation capability of radial basis function (RBF) neural ...
Application of global optimisation to particle identification using light scattering
(1998)
Numerical methods of solving the inverse light scattering problem for spheres are presented. The methods are based on two stochastic global optimization techniques: Deep's random search and the multilevel single-linkage ...
