FIBRE-OPTIC LASER-BASED SORTING MACHINE Russian patent published in 2014 - IPC B07C5/34 B07B13/00 

FIELD: physics.

SUBSTANCE: fibre-optic laser-based sorting machine comprises a device for transporting material to be sorted, a device for laser illumination of the material to be sorted, a laser beam scanning device, two or more image reading and processing devices and a device for removing defective materials. The device for laser illumination further includes an optical fibre whose input is connected through a focusing optical system to optical outputs of one or more lasers; the output of the optical fibre is connected to the focusing and cylindrical optical system of the laser beam scanning device. The image reading and processing devices are configured to read laser light reflected and transmitted through the material and read in different spectral ranges. The sorting machine further includes laser light intensity modulators.

EFFECT: high efficiency of sorting.
