Abstract
The performance of a typical machine vision system depends on the quality of the images that is directly affected by the illumination. In order to obtain high contrast images, the target must be illuminated in such a way that distinctions between target areas and peripheral areas are as clear as possible. A good design can improve the resolution of images and make software programming more easy, while a bad design will inevitably cause many problems. For example, specular reflection and exposal may hide important information, and hatching will blur the edges of images. So we present a new design of a light source called 24-phase colour light and various lighting techniques to improve the quality of the illumination.
