Abstract

L'INVENTION CONCERNE UN ELEMENT OPTIQUE HOLOGRAPHIQUE REALISE AFIN QUE LA DISTORSION QUI PEUT ETRE PRESENTE PENDANT LA RESTITUTION SOIT CORRIGEE. SELON L'INVENTION, UN PRISME R EST PLACE SUR L'UN DES DEUX FAISCEAUX LASER AU MOMENT DE LA CONSTRUCTION DE L'ELEMENT HOLOGRAPHIQUE AFIN QU'IL CREE DES ABERRATIONS QUI COMPENSENT LA DISTORSION QUI POURRAIT APPARAITRE DANS LE CAS CONTRAIRE. LES ELEMENTS OPTIQUES HOLOGRAPHIQUES FORMES PEUVENT ETRE UTILISES SANS DISPOSITIF OPTIQUE SUPPLEMENTAIRE, LORS DE LA RESTITUTION. APPLICATION AUX LENTILLES HOLOGRAPHIQUES POUR COLLIMATEURS DE PILOTAGE.THE INVENTION CONCERNS A HOLOGRAPHIC OPTICAL ELEMENT REALIZED SO THAT THE DISTORTION WHICH CAN BE PRESENT DURING THE RESTITUTION IS CORRECTED. ACCORDING TO THE INVENTION, AN R PRISM IS PLACED ON ONE OF THE TWO LASER BEAMS AT THE TIME OF CONSTRUCTION OF THE HOLOGRAPHIC ELEMENT SO THAT IT CREATES ABERRATIONS WHICH COMPENSATE THE DISTORTION WHICH COULD APPEAR IN THE OTHER CASE. SHAPED HOLOGRAPHIC OPTICAL ELEMENTS MAY BE USED WITHOUT AN ADDITIONAL OPTICAL DEVICE, WHEN RETURNING. APPLICATION TO HOLOGRAPHIC LENSES FOR PILOT COLLIMATORS.
