Lighting I: Principles,. This, in turn, is highly dependent on the quality of the lighting, optics, and sensor used to capture the image. As Uber (1986) has noted, ‘in designing an inspection system, the initial temptation is to aim a convenient light source at the unit being inspected, to obtain an image of the unit, and
