| 摘要 |
The invention relates to a sorting device and a method for sorting products (1) that are moved in a flow of products (2) through an inspection zone (3), wherein a light beam (6) is moved over the flow of products such that substantially all products (1) are hit by the light beam (6) in said inspection zone (3), whereby the light of this light beam (6) is, on the one hand, directly reflected as of the point of impact of the light beam on the products, and is, on the other hand, reflected in a scattered manner as of a zone round the point of impact following the diffusion of the light beam's light in the products, whereby the directly reflected light as well as the light which is reflected in a scattered manner is at least partly directed to a sensor element (19) of a detector (15), whereby this sensor element (19) has at least two detection areas, wherein for each detection area a detection signal is generated corresponding to the intensity of the reflected light (14) that impinges upon this detection area.
