Abstract (en)
A background for an electro-optical sorting machine viewing station where fungible products pass during sorting and are distinguished by being acceptable or nonacceptable in at least two spectral ranges comprising a first layer responsive to light reflectivity in a shorter spectral range and nonresponsive in a longer spectral range and a second layer behind the first layer and responsive to a longer spectral range that is received following penetration of the first layer. The first layer can be paint, transparent tape or a thin film. The second layer is preferably painted metal, plastic, wood or a wood and glue combination. <IMAGE>
