Abstract (en)
[origin: EP2085154A2] The method involves moving bulk goods (8, 9) in a material stream between an illumination unit (2) and a sensor (1) i.e. monochrome sensor, which is designed as a line scan camera or an area scan camera. Illumination with a predetermined wave length is implemented in a temporally or locally discrete manner using the illumination unit. Illumination is produced as a partial dark field illumination. Transmission signals are received by the sensor. The transmission signals are evaluated and bulk goods are sorted based on the evaluation. The illumination unit comprises light elements (3) i.e. high power LEDs, which are arranged outside a visible area (4) of the illumination unit. An independent claim is also included for a device for spectral based sorting of transparent and semitransparent bulk goods.
