Diffraction efficiency of low-resolution Fresnel encoded lenses

Appl Opt. 1994 Oct 10;33(29):6741-6. doi: 10.1364/AO.33.006741.

Abstract

A mathematical model to describe the behavior of low-resolution Fresnel lenses encoded in any low-resolution device (e.g., a spatial light modulator) is developed. From this model the diffraction efficiency is calculated in terms of all the parameters that characterize these lenses.
