Abstract
The apparatus of the invention comprises a lighting device for illuminating a component to be inspected to form a halo of light around a periphery of the component and a system for comparing the shape of the halo of light to a known acceptable shape. A camera may be used to detect the halo and a programmed computer may be used to perform image analysis of the shape of the halo to determine if it conforms to an acceptable shape.
