Abstract
The invention relates to an apparatus for determining the shape and/or size of small particles, comprising a cell into which the particles are placed, at least one light source for illuminating the particles, and at least one one-dimensional image sensor for measuring an image of the illuminated particles. The cell is embodied as a conduit through which the particles can be transported, and the image sensor is placed in the immediate vicinity of the conduit or into the conduit.
Claims7
An apparatus for determining the shape and/or size of small particles, comprising a conduit through which the particles can be transported, at least one light source for illuminating the particles, and at least one one-dimensional image sensor for measuring an image of the illuminated particles which is placed in the immediate vicinity of the conduit, in the near field (Fresnel zone) of the particles, wherein the apparatus comprises multiple light sources and image sensors that are grouped around the conduit for the formation of the image.
