METHOD OF ANALYSIS OF SUSPENDED MATTER Russian patent published in 2014 - IPC G01N15/02 

FIELD: measurement equipment.

SUBSTANCE: suspended matter is illuminated with a light beam, and an image of matter is recorded, using which the size and shape of the matter is determined. The light beam after passage of the flow is turned in respect to the initial beam and is again sent via the flow, where the image of the matter is recorded from four angles of the light flow. Therefore, there are four projections of the matter in the recording plane. Using the produced images, they decide on the size and shape of the matter of complex shape.

EFFECT: higher information value of data for assessment of non-spherical particles of complex shape and their orientation in space.
