The detection device includes first and second photodetectors each sensitive to two different wavelength ranges. The detection device comprises a first filter configured to allow the first wavelength range to pass and to block the second wavelength range. The first filter covers the first photodetector and leaves the second photodetector uncovered. The detection device comprises a second filter located at a distance from the first and second photodetectors and at a distance from the first filter. The second filter is configured to allow the first and the second wavelength ranges to pass. A processing circuit is configured to receive electric signals coming from the first and second photodetectors and to provide data relative to the radiation of the second wavelength range by comparing the first signal with the second signal.
