Abstract:
The visible and near-infrared radiation detector includes a near-infrared photosensitive element, a readout circuit for reading the near-infrared photosensitive element, four visible photosensitive elements, one of which being placed facing the near-infrared photosensitive element, and three interference filters to define a pixel quadruplet. A first pixel, including the near-infrared photosensitive element and one of the visible photosensitive elements, has no filter. The three other pixels, respectively including the three other visible photosensitive elements, are respectively provided with filters associated with the three primary colors. Each interference filter includes an alternation of metal layers and of dielectric layers.
