Abstract
A device for the detection of multi-spectral infrared and visible radiation using a bolometric detector having at least one active layer and two control electrodes for the detection of both infrared and visible radiation, and also using at least one photodetector having at least two active layers and two control electrodes for detecting solely visible radiation. The device is uncooled, and the two detectors are superimposed and combined with one-another for forming the same sensitive element.
Claims16
Device for the detection of multispectral infrared/visible radiation comprising:
- at least one bolometric detector (I) having at least one active layer (10) and two control electrodes and ensuring the detection of IR and visible radiation and
- at least one photoelectric detector (V) having at least two active layers (11, 12) and two control electrodes and solely ensuring the detection of visible radiation,
- characterized in that the bolometric detector and the photoelectric detector are of the uncooled type and that they are superimposed and combined with one another to form the same sensitive element.
