Device and method for detecting infrared radiation through a resistive bolometer matrix

摘要

An infrared radiation detection device comprising: a substrate; a matrix of at least one line of elements for detecting the radiation, each comprising a resistive imaging bolometer, the matrix being formed above the substrate; a bolometer reading circuit, a temperature measuring device for measuring the temperature in at least one point of the substrate; and a compensation circuit and data processing device for correcting the signal formed from each bolometer as a function of the temperature measured in at least one point of the substrate. The compensation circuit and data processing device capable of correcting the signal formed from the imaging bolometer by using a predetermined physical model of the temperature behavior of the signal.
