Abstract:
Infrared detection device comprising at least one first bolometer able to detect at least a part of infrared radiation intended to be received by the infrared detection device, and a reading and compensation circuit of a first electrical signal intended to be outputted by the first bolometer, with the reading and compensation circuit comprising at least: one second bolometer coupled electrically to the first bolometer and insensitive to the infrared radiation intended to be received by the infrared detection device; one first reading circuit of said first electrical signal from which is subtracted a second electrical signal intended to be outputted by the second bolometer; one second reading circuit of an electrical voltage at the terminals of the first bolometer and/or of an electrical voltage at the terminals of the second bolometer, comprising a plurality of switches.
