Abstract[German]
Ein diffraktives optisches Element (104) zum Kalibrieren einer Kamera (102) weist eine Mikrostruktur auf, die ausgeformt ist, um eine auf das diffraktive optische Element (104) einfallende monochromatische ebene Welle (108) in mehrere Beugungsordnungen mit unterschiedlichen aber bekannten Ausbreitungsrichtungen zu beugen, die eine Nullordnung umgeben, wobei jede der Beugungsordnung als ein Punkt eines Beugungsmusters auf einen Kamerasensor (112) der Kamera (102) projizierbar ist.[English]
A diffractive optical element (104) for calibrating a camera (102) has a microstructure which is shaped so as to diffract a monochromatic plane wave (108) incident on the diffractive optical element (104) into a plurality of orders of diffraction which have different but known propagation directions and surround a zero order, each of the orders of diffraction being projectable as a point of a diffraction pattern onto a camera sensor (112) of the camera (102).[French]
Un élément optique diffractif (104) d'étalonnage d'un d'appareil de prise de vues (102) présente une microstructure qui est formée de manière à diffracter une onde plane monochromatique (108) incidente sur l'élément optique diffractif (104) en une pluralité d'ordres de diffraction qui présentent des directions de propagation différentes mais connues et entourent un ordre zéro, chacun des ordres de diffraction pouvant être projeté en tant que point d'un motif de diffraction sur un capteur d'appareil de prise de vues (112) de l'appareil de prise de vues (102).
