摘要： In the field of multi-phase flows there is a need for a device and a method, for generating data relating to particles in a particulate material suspended in a fluid medium flowing within a pipe in a given direction, which provides more accurate data about the particles than conventional direct imaging techniques. A device (30; 50), for generating data relating to particles in a particulate material suspended in a fluid medium flowing within a pipe (34; 54) in a given flow direction (FD), comprises a light source (32) arranged to illuminate a portion of the flow, and an image acquisition unit (40) for capturing an image of the particles as they pass through the illuminated portion of the flow. The image acquisition unit (40) has a predetermined focal plane (41), and is arranged so that the focal plane (41) is inclined relative to the flow direction (FD) of the particles. The device (30; 50) also includes a processing unit which is in communication with the image acquisition unit (40). The processing unit enhances the image and processes the enhanced image to generate data relating to the particles captured therein. A method, for generating data relating to particles in a particulate material suspended in a fluid medium flowing within a pipe (34; 54) in a given flow direction (FD), comprises the steps of (i) illuminating a portion of the flow, (ii) arranging an image acquisition unit (40) having a predetermined focal plane (41) so that the focal plane (41) is inclined relative to the flow direction (FD) of the particles, (iii) capturing an image of the particles as they pass through the illuminated portion of the flow, (iv) enhancing the image, and (v) processing the image to generate data relating to the particles captured therein.
