Abstract
(EN)
Techniques are disclosed for systems and methods to provide improved ocular aberrometry. An ocular aberrometry system (100) includes a wavefront sensor (120) configured to provide wavefront sensor data associated with an optical target (102) monitored by the ocular aberrometry system (100) and a logic device (140) configured to communicate with the wavefront sensor (120). The logic device (140) is configured to receive (502) ocular aberrometry output data including at least the wavefront sensor data provided by the wavefront sensor (120), determine (504) estimated ocular alignment deviations corresponding to a relative position and/or orientation of the optical target (102) monitored by the ocular aberrometry system (100) based, at least in part, on the received ocular aberrometry output data, and generate (508) user feedback corresponding to the received ocular aberrometry output data based, at least in part, on the estimated ocular alignment deviations.

Les techniques selon la présente invention concernent des systèmes et des procédés fournissant une aberrométrie oculaire améliorée. Un système d’aberrométrie oculaire (100) comprend un capteur de front d’onde (120) conçu pour fournir des données de capteur de front d’onde associées à une cible optique (102) surveillée par le système d’aberrométrie oculaire (100) et un dispositif logique (140) conçu pour communiquer avec le capteur de front d’onde (120). Le dispositif logique (140) est conçu pour recevoir (502) les données de sortie d’aberrométrie oculaire comprenant au moins les données de capteur de front d’onde fournies par le capteur de front d’onde (120), déterminer (504) les écarts d’alignement oculaire estimés correspondant à une position et/ou une orientation relatives de la cible optique (102) surveillée par le système d’aberrométrie oculaire (100) sur la base, au moins en partie, des données de sortie d’aberrométrie oculaire reçues, et générer (508) un retour d’informations utilisateur correspondant aux données de sortie d’aberrométrie oculaire reçues sur la base, au moins en partie, des écarts d’alignement oculaire estimés.
