An adage you’ll hear among practitioners of machine vision is, “The sharper the image, the faster the system.” This saying harkens back to the fact that it is easier for an industrial- vision system to recognize parts when they are sharply defined. Backlighting, of course, is a widely used method for obtaining a sharp silhouette that is easy for a vision system to recognize. But backlighting is being pushed to its limits because of the need for ever- more throughput and accuracy. The problem is that the diffuse light sources normally used to backlight can produce diffuse reflections from an object being backlit. The result is softer-looking edges that take longer to recognize. And in some cases the soft edges make it impossible for the vision system to evaluate superfine details.
