  • Device and method intended to measure the properties of a complex medium by analysis of the variation in backscattered and/or transmitted light
    Patent number: 9110031
    Abstract: Disclosed is a device and method intended to measure the properties of a complex medium (2) by analyzing the variation in light backscattered by this complex medium (2) after a prior stirring step. The device and the method include movement element (14) capable of subjecting the receiving element (6) to a stirring movement including at least a back-and-forth movement along a directional vector extending by a not insignificant amount along the longitudinal direction, so as to generate shear stresses in the complex medium (2), thereby destroying aggregates in the complex medium (2) when a container (4) is received and supported by the receiving element (6).
    Type: Grant
