Abstract
A device for detecting infrared radiation including a resistive imaging bolometer, a mechanism for measuring drift in the electrical resistance of the bolometer relative to a reference value of the electrical resistance of the bolometer which corresponds to predetermined operating conditions of the bolometer, and a mechanism for correcting the effects of the drift in resistance or for correcting the drift itself.
