Fresnel lenses, when used as light condensors, generate many spurious ghost images due to multiple refraction and reflection of light between the facets and risers. In some applications, such as overhead projection, these images can be visible to the user. Using the technique of nonsequential ray tracing, the origin, direction, and intensity of these ghost images are analysed for two types of Fresnel lens doublet systems. Techniques for the reduction or elimination of these ghost images are also discussed.
