RT Journal Article T1 Diffractive optical elements with square concentric rings of equal width A1 Alda Serrano, Javier A1 Sánchez Brea, Luis Miguel A1 Salgado Remacha, Francisco Javier A1 Rico García, José María AB A diffractive optical element having equal-width concentric square rings is analyzed in this article. This constant width makes possible its realization using spatial light modulators or square pixels phase screens. It allows a simple analytical treatment, and the element is also simulated using the Rayleigh-Sommerfeld approach. An experimental verification of its performance has been compared with the simulated results.
