Abstract

As vision system projects move from laboratory investigations to factory floor installations, the absolute necessity of and advantages created by optimized lighting systems is being widely acknowledged. Frequently heard phrases such as "garbage in - garbage out", "the system can be no better than the image it starts with", and "if I could only get a little better contrast in the image, I could ..." attest to this acknowledgement. Furthermore, to quote Douglas Goodman, "In general, illumination is more critical in automated optical inspection than in visual inspection, since detectors and computer programs lack the dynamic range and forgiveness of the human visual system." The Machine Vision Association of SME attests to the interest in illumination by offering an Optics and Lighting session at Vision 86 and an Optics and Lighting hands on workshop.
