Title (EN) REFLECTIVE BIJECTIVE METHOD AND DEVICE FOR CODED APERTURE IMAGE ACQUISITION AND RECONSTRUCTION
(FR) PROCÉDÉ BIJECTIF RÉFLECTIF ET DISPOSITIF POUR ACQUISITION ET RECONSTRUCTION D’IMAGE À OUVERTURE CODÉE
Abstract:
(EN) A bijective coded aperture system uses mirror system with a multitude of reflector elements attached to an absorbing, such as black, substrate. Each of the reflector elements is independently placed at a different angle with respect to each other in such a manner that the image of the scene is replicated several times at the focal plane and on the image sensor. Moreover, these replicated images may be overlapping. An image processor can then execute reconstruction methods of the image to faithfully represent the scene.
(FR) La présente invention concerne un système d’ouverture codée bijectif qui utilise un système de miroir avec une pluralité d’éléments réfléchissants fixés à un substrat absorbant, par exemple noir. Chacun des éléments réfléchissants est indépendamment placé à un angle différent par rapport aux autres de telle manière que l’image de la scène soit répliquée plusieurs fois au plan focal et sur le capteur d’image. De plus, ces images répliquées peuvent être superposées. Un processeur d’image peut ensuite exécuter des procédés de reconstruction de l’image afin de représenter fidèlement la scène.
