Simultaneous encoding of amplitude apodizers and Fresnel lenses in spatial fight modulators

In this paper we show a technique to simultaneously encode a Fresnel lens and an amplitude filter in a single diffractive optical element (DOE) displayed on a spatial light modulator (SLM). In particular we have displayed this new DOE, which we call amplitude apodized Fresnel lens (AAFL), on a twist...

We provide a method to encode the complex amplitude information of the AAFL on a phase-only function.
