As the analysis and processing sophistication has increased in machine vision applications, the type of application has extended to the more difficult tasks of inspection. One such area is high speed inspection requiring high light levels. Occasionally, high speed inspection can be addressed through the use of strobes, but otherwise large amounts of light may be necessary. A variety of high efficiency lights have emerged for use in applications beyond machine vision, which may now be adapted to use with vision applications. These sources include high pressure gases, stable arcs, and solid state sources. This paper presents experimental data characterizing some of these new sources, and explores the experimental match between these sources and the spectral response available from the latest solid state video cameras. In order to better understand the restrictions on the use of these sources, and how they may be overcome, this paper suggests the use of graphical models of the light source performance.
