MEASURING METHOD OF GEOMETRICAL PARAMETERS OF NON-SPHERICAL PARTICLES IN LIQUID AS PER DEPOLARISED DYNAMIC LIGHT SCATTERING AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2015 - IPC G01N15/02 G01N21/47 

Abstract RU 2556285 C1

FIELD: instrumentation.

SUBSTANCE: method consists in measurement of relationships between intensity of scattered radiation and time at several positions of a polarisation analyser, which are intermediate between the position, in which radiation is passed with linear polarisation coinciding with polarisation of exciting radiation (VV) and the position in which radiation is passed with polarisation perpendicular to polarisation of exciting radiation (VH).

EFFECT: invention allows avoiding the need for measurement of very weak optic signals specific for intensity of scattered radiation at polarisation VH.
