Abstract
A photo-optical detector for use in a multi-chromatic sorting machine, each detector including at least two separate photodiode materials responsive to a different spectral range and a multi-peak optical filter having transmission response characteristics that are respectively defined in a frequency spectrum of the respective spectral ranges of the materials. The sorting machine using such detectors can be selectively programmed using the various resulting signals from the detectors after appropriate amplification and threshold detection to cause resulting ejection mechanism activation.
