The present invention provides an apparatus and method for determining a relative positional and rotational offsets between a first and second imaging device. In exemplary embodiments, the present invention can be used to determine the relative offsets between a Hartmann-Shack wavefront sensor and a pupil camera. Calibration apparatus (12) includes a body (48) that may include openings (50) for receiving a calibration rail. A rotatable and translatable body (54) has a centered cross-shaped aperture (20) which is movable coupled to body (48).
La présente invention concerne un appareil et un procédé permettant de déterminer des décalages relatifs de position et de rotation entre un premier et un second dispositif d'imagerie. Selon certains modes de réalisation, cette invention peut être mise en oeuvre pour déterminer les décalages relatifs entre un capteur à front d'onde de type Hartmann-Shack et un appareil de prise de vues à pupille. Un appareil d'étalonnage (12) selon l'invention comprend un corps (48) qui peut comporter des ouvertures (50) pour recevoir un rail d'étalonnage. Un corps rotatif et mobile (54) comporte une ouverture centrale (20) en forme de croix qui est reliée au corps (48) de façon mobile.
