Such diffusers are necessary to avoid problems of speckles. © OSA 2016.Recurso electrónicoapplication/pdfenghttp://creativecommons.org/licenses/by-nc-nd/4.0/info:eu-repo/semantics/conferenceObject10.1364/LAOP.2016.LTu3A.2PhotonicsBandlimitedFractional fourierFractional Fourier transformsFresnel domainsPhase ambiguityDiffusers (optical)info:eu-repo/semantics/restrictedAccessAtribución-NoComercial 4.0 InternacionalUniversidad Tecnológica de BolívarRepositorio UTB571906884597202230088670166425956270896900
