A system and method improves a quality of sensor image data from a wavefront emanating from an eye. The sensor image data include a pixel array of intensities. A filter array is populated with a coefficient at each position of the array and the filter array is applied to each position in the pixel array. The system includes a processor and a software package adapted to perform the above method steps.

Cette invention concerne un système et une méthode qui permettent d'améliorer une qualité de données d'image de détecteur à partir d'un front d'ondes émanant de l'oeil. Les données d'image de détecteur comprennent une matrice de pixels d'intensité. A chaque emplacement de la matrice de filtre est assorti d'un coefficient. La matrice de filtre est appliquée sur chaque emplacement de la matrice de pixels. Le système comprend un processeur et un logiciel conçus pour exécuter les opérations ci-dessus.
