This device for detecting infrared radiation comprises a one or
two-dimensional array of elementary bolometric detectors, that are
electrically connected to a readout circuit (1), which is associated with
a compensation structure intended to divert most of the background or
common-mode current that flows through each of the bolometric detectors
in the array.The compensation structure consists of a layer that
incorporates at least one bolometric material (8) extending between two
electrical connection areas (3, 6, 7) linked to the readout circuit
(1).The layer that incorporates the bolometric material (8) that
constitutes the compensation structure is itself in thermal contact with
the substrate that constitutes the readout circuit (1) outside the
electrical connection areas (3, 6, 7).
