The purpose of the illumination is to enhance the contrast of the object in a way that the desired feature is detectable by the MV system. On the basis of interaction of the light with the surface of the object a detectable contrast is created. Important is which portion of the light is absorbed and which is reflected or transmitted back to the camera.
