Abstract
An illumination source for a machine vision viewer for a sorter that provides a flow of articles along a scan line includes an elongated, cylindrical shroud with illumination sources mounted interior of the shroud. The illumination sources are arranged longitudinally within the shroud and are angularly spaced along the inner circumference of the shroud. Linear slots running parallel with the shroud axis are provided in the shroud for the subject articles to enter and exit the shroud. A linear slot running parallel with the shroud axis is provided for receptors to view the articles passing through the shroud. The cylinder interior is otherwise uniform and light reflecting. An alternative embodiment of the shroud comprises two shroud arc components with openings between the arcs to allow articles to pass between the shroud arc components.
