Title
(EN) OPTICAL SYSTEM USING A RADIAL HARMONIC PUPIL FILTER FOR GENERATING COLLIMATED BEAMS
(FR) SYSTEME OPTIQUE DE PRODUCTION DE FAISCEAUX COLLIMATES AU MOYEN D'UN FILTRE A PUPILLE METTANT EN OEUVRE UNE FONCTION HARMONIQUE RADIALE
Abstract
(EN)
A Fourier hologram, placed at rear focal plane (Pi), with the distribution of a radial harmonic function creates, in the far field, near focal plane (Pf), a pseudo non-diffracting beam. The properties of this pseudo non-diffracting beam can be set by appropriate characterization of the radial harmonic function. Various operations can also be carried out to change the position of the beam relative to the focal point (Z=0). The beam can be shifted in space, twisted, or tilted.
(FR)
Un hologramme de Fourier, placé au niveau d'un plan focal arrière (Pi), reprenant la distribution d'une fonction harmonique radiale crée, dans le champ lointain, plan focal proche (Pf), un faisceau imitant l'absence de diffraction. Les propriétés de ce faisceau imitant l'absence de diffraction se définissent en affectant à la fonction harmonique radiale les caractères appropriés. Il est également possible d'effectuer diverses opérations pour modifier la position du faisceau par rapport au foyer (Z=0). Le faisceau peut être spacialement décalé, tordu ou incliné.
