Abstract
A method for the quantitative acquisition of flow patterns in fluid flows in which a medium (e.g., a gas or a liquid) and the particles contained therein and carried in the flow are set in motion in a transparent flow object. The method provides that a flow object is transilluminated by a laser light fanned out on a plane parallel to the longitudinal axis of the flow object. A scattering of the laser light by the particles is detected by a camera positioned at a right angle to the longitudinal channel axis and moving in the vertical and horizontal directions, and can be analyzed with an analysis unit connected downstream from the camera. The analysis unit is calibrated by quantitatively comparing an image, which has an object-to-image ratio and which is recorded inside the flow object by the camera, to an image having an object-to-image ratio and recorded outside the flow object.
