Title
(EN) WAVEFRONT MEASUREMENT
(FR) PROCEDE DE MESURE DE FRONT D'ONDE ET APPAREIL ADAPTABLE A UNE GAMME DE DIAMETRES DE PUPILLE
Abstract
(EN)
An apparatus and method for measuring wavefront aberrations. The apparatus comprises a magnification device for magnifying the wavefront, a wavefront sensor for capturing information related to the magnified wavefront, and a processor for calculating aberrations of the wavefront from the captured information. The method comprises receiving the wavefront emitted from the pupil at an adjustable lens assembly, adjusting the magnification of the adjustable lens assembly such that the magnified wavefront is optimized for use with the wavefront sensor; and passing the magnified wavefront to the wavefront sensor.
(FR)
L'invention concerne un appareil et un dispositif pour la mesure des aberrations de front d'onde. L'appareil comporte un dispositif d'amplification de front d'onde, un capteur à front d'onde recueillant l'information liée à cette amplification, et un processeur permettant de calculer les aberrations à partir de l'information. Le procédé consiste à recevoir le front d'onde émis par la pupille au niveau d'un ensemble lentille réglable, à régler l'amplification de cet ensemble pour optimiser le front d'onde amplifié aux fins d'utilisation par le capteur, et à transmette le front d'onde amplifié au capteur.
