Abstract

A vision apparatus for indicating the locations of edges of work pieces in an illuminated work area including several arrays where each array includes several light conducting fibers. One end of the array is positioned in the work area to be illuminated by light except when blocked by the object. The other end of the optical fibers are positioned in a matrix plate contained within a camera enclosure. The camera enclosure further includes a lens to optically couple light from the matrix plate optical fiber ends to a light sensing device that produces electrical signals indicating the presence or absence of light at each of the fiber ends.
