摘要： The invention relates to a device for determining the particle size and/or the particle shape of particles (T) which are guided through a measurement path (M) as a particle stream, comprising an illuminating device (4) for illuminating the particle flow in the measurement path (M) from the rear side, a camera (5) for capturing shadow projections of particles (T) illuminated by the illuminating device (4) from the front side, and an analyzing unit (7) which determines the particle size and/or particle shape of the recorded particles (T) using the captured images of the camera (5). The camera (5) is paired with a projection device (6) which is arranged on the front side of the measurement path (M) and positioned at a triangulation angle α relative to the camera (5) in order to project a light line (L) onto the particles (T) of the particle flow in the measurement path (M), said light line being captured by the camera (5). Depth information and/or geometric information on the detected particles (T) is ascertained from the shape of the light line (L) in the analyzing unit (7).

摘要： The invention relates to an apparatus (1) for determining the particle size and/or the particle shape and/or the optical properties, such as transparency, of particles (2) in a particle stream (3). Said apparatus comprises: a feed device (4) for feeding the particles (2) to a measurement zone (5), the particles (2) flowing through the measurement zone (5); at least one lighting device (6) for lighting the measurement zone (5); at least two camera devices (7, 8), each recording a measurement region (9, 10) of the measurement zone (5) associated with one of the camera devices (7, 8), a first camera device (7) recording a first, preferably larger, measurement region (10) with a first, preferably lesser, magnification, and a second camera device (8) recording a second, preferably smaller, measurement region (9) with a second, preferably stronger, magnification; an imaging optics (11) for imaging the measurement regions (9, 10); and an evaluation device for determining the particle size and/or the particle shape from the images of the measuring regions (9, 10), the imaging optics (11) having at least one optical element (14) on which and/or by which the light radiation emitted by the measuring zone (5) is split up into at least two radiation parts. The lighting device (6) is designed such that the first measurement region (10) and the second measurement region (9) are always lighted jointly, the first measurement region (10) being lighted with the same intensity as the second measurement region (9).
