Title
(DE) BAYER-MATRIX-BILDSENSOR
(EN) BAYER MATRIX IMAGE SENSOR
(FR) CAPTEUR D'IMAGE À MATRICE DE BAYER
Abstract
(EN)
The invention relates to an image sensor comprising: • an optical system (2a) for receiving an optical signal; • a Bayer matrix (4) located on the image focal plane of the optical system (2a), the Bayer matrix (1) comprising: a reference optical filter (B1) configured to eliminate or attenuate, in the received optical signal, a first band of wavelengths and to allow through, in the received optical signal, a second band length of wavelengths, and also eight optical filters adjacent to the reference optical filter (B1); • a phase mask (2c, 22, 28) arranged on a pupil (2b) of the optical system (2a) and configured to selectively project at least 98% of the energy of the optical signal carried in the first band of wavelengths and 98% of the energy of the optical signal carried in the second band of wavelengths on the reference optical filter (B1) and on at least one adjacent optical filter, which is configured to allow through, in the received optical signal, the first band of wavelengths.

L'invention concerne un capteur d'image comprenant : • un système optique (2a) pour recevoir un signal optique, • une matrice de Bayer (4) située au plan focal image du système optique (2a), la matrice de Bayer (1) comprenant : un filtre optique de référence (B1) configuré pour éliminer ou atténuer dans le signal optique reçu une première bande de longueurs d'onde et pour laisser passer dans le signal optique reçu une deuxième longueur bande de longueurs d'ondes, et par ailleurs huit filtres optiques adjacents au filtre optique de référence (B1), • un masque de phase (2c, 22, 28) agencé sur une pupille (2b) du système optique (2a) et configuré pour projeter au moins 98 % de l'énergie du signal optique transportée dans la première bande de longueurs d'onde et 98 % de l'énergie du signal optique transportée dans la deuxième bande de longueurs d'onde sélectivement sur le filtre optique de référence (B1) et sur au moins un filtre optique adjacent lequel est configuré pour laisser passer dans le signal optique reçu la première bande de longueurs d'onde.
