A device for detection of radiation genesis bolometric a sensor polarized, application is an infrared detection

摘要

This device for detecting electromagnetic radiation, comprises at least one pixel (10) of the detection of radiation (ir) for the provision of an electric current (i, im) representative of the radiation detected. The pixel (10) comprises a detection circuit (18) comprising a bolometric detector (20) connected in series with means (22) of the bias voltage. The device further comprises a circuit (34) of the bias current of the bolometric detector (20), different from the detection circuit (18), connected to the bolometric detector (20) at a point (36) of the detection circuit (18) situated between the bolometric detector (20) and the means (22) of the bias voltage.
