Paper Abstract

Virtual image systems, in which a presentation of a scene appears to lie at infinity, play an important role in a variety of training devices. Significant advantages are gained through the use of dioptic systems, but the sizes of optical elements required has hitherto prevented their use. This situation has been radically changed with the development of methods of making precision Fresnel lenses. The application of such Fresnel lenses to a specific application is discussed in detail. Two versions have been developed, one with chromatic correction and one without chromatic correction. The result of this work shows that it is feasible to use combinations of Fresnel lenses in systems to be used for virtual image display.
