Machine vision systems are a necessary part of many modern manufacturing processes such as electronic assembly involving fine pitch devices. One of the most difficult tasks in the development of a machine vision system is the design of an illumination system which can reliably generate images suitable for machine processing. Design of a lighting system requires information on the reflective properties of the materials to be imaged. Of particular importance is information concerning the directional and spectral reflectances of the materials.
