Abstract

Fiber optic illumination offers major advantages, but the light collection and delivery system can limit performance. In many pattern recognition and measurement systems available light can limit performance when a relatively high f/# is required (for image quality or depth of field), or when spectral and polarization filtering is used (for contrast enhancement). In this paper fiber optic light source collection and delivery is analyzed, using both a model based approach and lab measurements of commercially available sources. It is shown that proper selection of sources, reflectors, and bundle diameters can result in significant improvements in efficiency. Such data will be useful to system designers and could lead to improvements in commercially available light sources.
