Bastiaans appreciates the hospitality at Universidad Complutense de Madrid.Based on the ray transformation matrix formalism, we propose a simple method for the identification of the dynamic and geometric parts of the Gouy phase, acquired by an appropriate Gaussian-type beam while propagating through a first-order optical system.engDynamic and geometric phase accumulation by Gaussian-type modes in first-order optical systemsjournal articlehttp://www.opticsinfobase.org/ol/abstract.cfm?uri=ol-33-15-1659http://www.opticsinfobase.org/open access535Fractional fourier-transformsOrbital angular-momentumLight-beamsRepresentationÓptica (Física)2209.19 Óptica Física
