ABSTRACT:
A product discrimination system using a fiber optic sensing system and a line scan camera sensor for recalibration of the fiber optic system. A plurality of fiber optic sensing stations measure reflected light spectra of products conveyed past the stations. The line scan camera is positioned adjacent one of the fiber optic sensors at one of the stations. A standard object is positioned adjacent conveyor so as to also be viewed by the line scan camera. The line scan camera recalibrates itself based on the standard object and is compared with the adjacent fiber optic station to recalibrate results from the fiber optic system.
