Capture
Controlled lighting and camera alignment help reveal differences in the product stream.
From a pixel to a sorting decision.
How illumination, RGB sensing, FPGA processing and timed ejection work together in an optical sorter.
Overview
An optical sorter presents material to an illuminated inspection area, captures its appearance, classifies what it sees and coordinates a timed separation. T20 catalogue specifications describe CCD linear imaging and FPGA data acquisition. COMMANDOR documentation describes FPGA signal processing and study-data classification. Sensor and processor specifications vary by model; use the published technical sheet for your selected machine.
Machine features
Classify
RGB pixel comparison identifies colour differences. Image processing can evaluate additional visual features, depending on the machine.
Separate
The rejection decision is synchronized with material travel and valve timing.
