Abstract

We describe the Fresnel field of pixelated diffractive elements with simple formulas. These formulas are employed to compute the reconstruction field of finite Talbot array illuminators and to analyze the performance of pixelated lenses. A simple relation to analyze the diffraction efficiency of pixelated lenses is presented. We also show that a pixelated lens with the appropriate parameters exhibits an apodized point spread function that is originated in the finite size of the pixel's pupil. This effect, that we call self-apodization, is experimentally verified by encoding a one-dimensional pixelated lens onto a liquid crystal spatial light modulator.
