RT Journal Article T1 Diffractive performance of square Fresnel zone plates A1 Alda Serrano, Javier A1 Rico García, José María A1 Salgado Remacha, Francisco Javier A1 Sánchez Brea, Luis Miguel AB We analyze the optical behavior of square Fresnel zones plates. A theoretical analysis and numerical simulations based on the Rayleigh-Sommerfeld approach have been developed analyzing properties such as the depth of focus and the intensity of the focus in terms of the number of zones. In addition, an experimental verification has been performed using a Spatial Light Modulator to implement the designed square Fresnel zones plates.
