Abrégé

The present specification generally relates to the field of imaging device and particularly discloses an imaging device for detecting infrared radiation. The imaging device comprises a first set of detectors responsive to infrared electromagnetic radiation in a first wavelength band, a second set of detectors and a filter disposed above the second set of detectors to prevent registration of electromagnetic radiation outside a second wavelength band at the second set of detectors. The second wavelength band is a subset of the first wavelength band. The imaging device is configured to detect a deviation from an expected value of a level of electromagnetic radiation in a third wavelength band based on signals obtained from the first set of detectors and the second set of detectors. The third wavelength band is within the first wavelength band and outside the second wavelength band.

• G01J 5/00 - Pyrométrie des radiations, p. ex. thermométrie infrarouge ou optique
• G01J 5/58 - Pyrométrie des radiations, p. ex. thermométrie infrarouge ou optique en utilisant l’absorptionPyrométrie des radiations, p. ex. thermométrie infrarouge ou optique en utilisant un effet d’extinction
• G01J 5/10 - Pyrométrie des radiations, p. ex. thermométrie infrarouge ou optique en utilisant des détecteurs électriques de radiations
