Abstract
A device for detecting infrared radiation including a matrix of resistive imaging bolometers above a substrate, a read circuit forming an analog electrical signal constituting an image of the infrared radiation impinging on the matrix, a probe for measuring the temperature of the substrate, an ADC for converting the analogue electrical signals from the read circuit and probe, and a data processing unit for correcting the signal formed by the read circuit according digital values NC(i,j) corresponding to electrical signals from the bolometers exposed to a uniform scene at the measured temperature of the substrate. The data processing unit including a unit for computing the digital values NC(i,j) based on a single set of parameters of a predetermined physical model of the read circuit electrical signals and corresponding to the exposure of the matrix of imaging bolometers to a temperature substantially equal to the measured substrate temperature.
