Dynamic light scattering based microrheology of complex fluids with improved single-scattering mode detection

摘要: A fluid characterization measuring instrument is disclosed that comprises a sample vessel for bulk complex having capacity substantially larger than domain size of the and sufficiently large to cause scattering effects exceed surface sample, coherent light source positioned illuminate in first fibre end receive backscattered from after it has interacted with sample. The can also be close enough an optical axis decrease contribution multiply scattered light. further comprise photon-counting detector second fibre, correlation logic responsive single-scattering property analysis operative derive at least one fluid.
