ABSTRACT:
The invention relates to a device for detecting an electromagnetic radiation comprising a resistive imaging bolometer sensitive to the electromagnetic radiation to be detected, intended to be connected electrically to a signal shaping circuit, and a resistive common mode rejection bolometer that is associated electrically with the imaging bolometer, so that the current flowing through the common mode rejection bolometer is subtracted from the current flowing through the imaging bolometer, wherein it comprises means for controlling the resistance of the common mode rejection bolometer by injecting current therein.
