A wavefront sensor includes an afocal relay stage for magnifying an incoming wavefront reflected from a source plane. In an exemplary application, a retina of an eye reflects an impinging light beam thereon to form a series of wavefronts. A lenslet array (23) is positioned at a reference plane (22) of the afocal relay stage (21) to receive the magnified wavefront. Further downstream is positioned a means (25) for imaging and demagnifying a focal plane image (249) of the lenslet array (23) at a final image plane (26). This demagnified image then serves as input to an anlyzer, such as a charge-coupled- device (CCD) camera.

La présente invention concerne un capteur de front d'onde comprenant un élément de relais afocal servant à agrandir un front d'onde entrant réfléchi depuis un plan source. dans un exemple d'application de l'invention, la rétine d'un oeil réfléchit un faisceau de lumière incidente, pour former une série de fronts d'onde. Un réseau de petites lentilles est placé au niveau d'un plan de référence de l'élément de relais afocal, afin de recevoir le front d'onde agrandi. De plus, en aval se trouve un élément permettant la représentation et la réduction de taille d'une image de plan focal du réseau de petites lentilles au niveau d'un plan d'image finale. L'image à taille réduite est alors utilisée à l'entrée d'un analyseur tel qu'une caméra à dispositif de couplage de charge (<i>charge-coupled-device</i> / CCD).
