    Diffractive optical elements with square concentric rings of equal width
    (John Wiley & Sons INC, 2010-04) Alda, Javier; Sánchez Brea, Luis Miguel; Salgado Remacha, Francisco Javier; Rico-García, José María
    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.
