Paper Abstract

A mathematical model to describe the behaviour of low resolution Fresnel lenses encoded in low resolution device is developed. The effects of low resolution codification, such the appearance of new secondary lenses, are studied for a general case. Simple expressions for the light distribution in the focal plane and its dependence on the encoded focal length are developed. For a given codification device, an optimum focal length is found for best lens performance.
