ABSTRACT:
A device for detecting infrared radiation comprising an array of bolometric detectors which are sensitive to incident radiation and are referred to as “active” and a bolometer which is insensitive to said radiation and is referred to as “blind” formed on a substrate in which a read circuit is produced for sequentially addressing each of the rows of detectors of the array, each of the active bolometers in a single row being biased simultaneously. The read circuit also comprises means of producing a reference current (Iref) based on the blind bolometer; means of simultaneously copying the reference current (Iref) for each column of the array; and a plurality of current integrators, each associated with one column of the array and each designed to integrate the difference between the current flowing through the active bolometer of the row which is currently being read and said thus copied reference current.
