DETECTOR OF VISIBLE AND NEAR-INFRARED RADIATION

摘要

The invention relates to a detector of visible and near-infrared radiation, including: an element (36) that is photosensitive in the near infrared region; a circuit for reading the element that is photosensitive in the near infrared region; four elements (32) that are photosensitive in the visible region, one of which is placed facing the element (36) that is photosensitive in the near infrared region; and three interferential filters (50a-c), in such a way as to define a quadruplet of pixels. A first pixel (46) comprising the element (36) that is photosensitive in the near infrared region and one of the elements (32) that are photosensitive in the visible region does not have a filter. The three other pixels (48a-c), respectively including the three other elements (32) that are photosensitive in the visible region, are respectively provided with filters (50a-c) associated with the three primary colors. Each interferential filter (50a-c) includes alternating metal and dielectric layers.
